Pride has always been political ???

always political? like what?
.
Was Pride involved in

Canadian elections?
USA elections?
BREXIT?
ISIS?
Somalia?
Afghanistan
Iraq?

Pride has been political only on the politics of gay pride and rights
period
.
all other non-gay politics is not part of Pride's mandate
it merely waters down the gay message
.
or it should be political only if it pushes a leftist political agenda - is this what you mean?
