I disagree because history has shown this is the way it goes. For example, it did happen for gay men to a large extent in the western world. This is a gross generalisation for the sake of discussion on here, but until recent decades almost all gay men had to hide and needed spaces where they could just be themselves with like minded and mostly gay people. The outside world eventually changed and then these spaces became more open to non gay people. Not everyone in those communities was happy with that but many felt it was the price to pay for general acceptance and improved equality. See what happened to the Castro area gay bars in S.F. and the debates about the fact that they became popular with straight people once being gay became accepted in general society.
The idea isn’t that marginalised groups should hide and not mingle at all but that they should have a refuge they can retreat to because the outside world is too harsh right now.
