youre basically questioning the whole philosophy of intersectionality - the addition of stripes based on race is done as a tacit show of support against racism in the LGBT community
white people aren't excluded in LGBT spaces based on their race so no it's not tribal
sure showing support to possibly discriminated minorities in lgbt is an all-around good thing to do, but this is very much the wrong way to go about and do it---this shows support only in spirit and reallybthe only people that care about it are those against it, along with people who think that doing this actually does anything apart from provoking anti-lgbt and/or anti-black people against them
what im getting at is that if you want to show support to something, don't just say "black lgbt matters too" and slap them on something official, actually do something and don't change what's already working beautifully for the vast majority. doing this doesn't help in any good form, in fact it's quite the contrary
