They very well could be racist, sexist, homophobic, etc.
I actually just don't see how someone could be microaggressive as a homophobe
Maybe passive aggressive as a sexist...like..."here lemme help ya with that, honey," to a random woman pulling her luggage or something lol if you get the right (or wrong) woman haha, she'll say, "hey dickhead, I got it!
"
I really need an example of microaggression through homophobia though...
But definitely I get microaggression as racism. Because people are way more wary about being overtly racist because well it's illegal, thankfully. So they still exhibit their racist ideas through indirect behaviour which is annoying yes but still not a care of mine as long as my personal space and personal life aren't being affected by it.
I do agree it's rather hypercritical *and hypocritical!* to pay attention to microaggression about micro stuff like that lol but in certain situations like people's senses and awareness are heightened especially if you're the only minority around.
