Super straight isn't rlly that transphobic..
I mean straight is a sexuality after all, and (most) aren't saying "oooh fuck trannies" or any offensive stuff rlly, It's just a preference, just how lesbians prefer women, gay men prefer men, and some people prefer tall people over short ones excluding other groups.. There's a bunch of other ridiculous sexualities out there, I bet if this was 'Super gay' or 'Super lesbians' ya'll wouldn't care much and would say (ThEY cAN dAte WHoEveR thEy WanT)
