I really hesitate to air any views on this - it's fraught with pitfalls and complexities.
However I'm internally battling with a few questions at the moment and this is a "pub philosophy" thread (well it wasn't originally of course

).
I'm struck by Stu's comment. Most of us are approaching this from a "whitey" standpoint. We cannot speak for other viewpoints. To speak on their behalf is presumptious and patronising I feel. That does not preclude expressions of support for other viewpoints. It could also be said that certain ways of talking about 'minorities' actually makes things worse - adding 'victim' status is not helpful. And what is a 'minority'? 5% of something? 49%? It's also rarely the case that the 'minority' has one common feature - there are many overlapping ones some of which may even contradict the main minority 'label'.
The existence of 100% 'white' groups and stating that this is not 'representative' or 'equality' is fairly meaningless. Do the unrepresented people
want to be represented? The group cannot magic up a representative simply because one isn't present but 'should' be. That can only happen once an unrepresented person introduces themselves and asks the others to accept them. The others will either do so or not - and if not, it will be on the basis of 'discrimination' or 'dislike'.
Also the person attempting to join a group has a responsibility to present themselves as 'acceptable' to the group or to convince the group they fit in, or would benefit the group if the 'fit' did not currently exist. Otherwise we are patronising the joiner.
What is the dividing line between 'discrimination' and 'dislike'? Comments above imply that 'dislike' of an individual is ok, or at least cannot be helped in some way. But 'discrimination' is not ok.
If you dislike someone should you still be
forced to accept them? Or censured for not accepting them? Perhaps the dislike is because you do not like gravel bikes and they do. Should you be forced to accept them? Perhaps it is because their skin is black (or equally the case of a white person attempting to join an all-black group - it works both ways!)? I think it's pretty clear the former is ok but the latter isn't. Personally, if for example a 'non white skinned' person introduced themselves to the WRT Lonely Hearts Club it wouldn't even cross my mind not to 'accept' them or even register the fact. However if I later discovered that they were a - gasp - gravel bike fan, am I then allowed to think about it and even potentially 'reject' them?
But why is it clear one thing is ok but the other isn't? Both are characteristics of the person trying to be accepted. Is it because black skin is something that cannot be 'helped' - one is born with it- but gravelbiking is a choice formed after birth and therefore 'fair game'?
Ok that seemed fairly clear cut. But someone above mentioned one is not allowed to discriminate on grounds of skin colour, religion or sexual orientation. But a strong case could be made that 'skin colour' is something you have no choice over and makes no difference to your attitudes/characteristics. Same with sex, although some would argue there is sometimes an element of choice there. However, religion and politics? They seem no different to gravelbiking, and therefore fair game for 'dislike' and therefore rejection by the group if they do not wish to absorb those opinions and views. It can be argued that one is not born 'Christian' or 'Socialist' or whatever. Or are you? Maybe it's part birth and part environment/nurture? And the latter becomes more of a choice. I cannot choose being black so don't discriminate against me but feel free to do so because you don't like my politics/religion which I had some influence over. I would say religion and politics are hugely influenced by environment and nurture. So they are in the ground between discriminate and dislike - but where in that ground?
Many political and religious features can cross onto the list of someone's 'dislikes' (eg support for the death penalty or support for banning women from driving) and therefore fair game for exclusion by a group who do not like those opinions/views. Therefore it is not 'discriminatory' to resist integrating a person who likes something you dislike?
So again, someone define the difference between 'discriminate' and 'dislike' before we argue about whether one is reasonable or not.
Oh and I shall mention again my view that 'race' is a meaningless term so cannot be discriminated against. It can? Please clearly define 'race' for me then. It isn't 'black' or 'African' - ALL of us were black and African once. To do with borders? There are no borders really. Is race skin colour? We've agreed that cannot be discriminated against or disliked. Or is it attitudes / music / religion / politics / food choices / gravelbiking? Ah, now we're back to things that could just be
disliked....
Hmm.
In defence against what would appear to be my ambivalence/detachedness, I would say I'd initially welcome anyone into the WRT LHC because everyone is a
human being - until we discovered they were gravelbikers and/or D Trump, at which point 'dislike' might well kick in

....
And now... back to the studio.....
