I mean, they're not wrong to assume that's a tranny, or at least something close enough to it. It's a man pretending to be a woman. Trannies are just a protected class now so anything that pokes fun at them is a no go, let alone anything that shows them in a bad light.This character, from only those few lines, has of course automatically assumed trans and therefore the scene is transphobic and evil in these people's eyes.
