Maybe? The fear of clowns is often rooted in the uncanny. The obscuring makeup of clowns makes their emotions and expressions either so overly exaggerated or difficult/impossible to read which messes with the lizard brain and makes them seem to some people, particularly ones who have issues with reading facial cues, as inhuman. It's sort of the same principle that freaks people out about dolls and mannequins. That almost but decidedly not quite human alarm.
Drag makeup generally serves the opposite purpose. It is exaggerated but in such a way as to be easier to read the performer's face at a distance.
Trans person maybe, some of us are subject to our own personal problems just like anyone... But a concensus of trans people should be the marker. I don't know how many times I have heard someone claim allyship when they are being called out by multiple trans people for something they said or did.
It's interesting how fast some people will flip. Sometimes a well meaning cis person will suggest something as a work around for some trans engineered social convention or accommodation to try and make things easier for them without realizing how it interacts with the actual experience of being trans. When trans people try and explain exactly why it does not work based off of experience the cis person, upset their idea to solve a problem that they do not fully understand was rejected , suddenly start into the old transphobic gems - "oh you're just trying to be difficult, play the victim, nobody will like you if you're that sensitive"
End of day Trans allyship does involve a certain amount of trusting trans people to tell you what makes them comfortable and what they need because it really is a very different experience of gender at it's core. Deciding what we need on our behalf or telling us how we should feel or giving us advice on how to approach transness happens a lot out in the world and it really isn't helpful. It often just exposes how much the speaker does not understand.
