Some good suggestions already here, so I'mma put up my own queer fem experience;

• Calling stuff "woke" in a negative sense. It's a pretty damn big code for "I hate people and blame my own insecurities on them". They might view us as "snowflakes", but when we get criticised, we actually tackle it (when it's constructive criticism), when they won't even take the latter one.

• Being rude and verbally/physically violent, insisting. Being civil, compassionate, and accepting is a sign of better personality.

• Not letting me finish my sentences or talking in noisy environments. Wait your damn turn or until I can understand you!

• Smoking (don't care which type). I'm not going for someone who doesn't take care of themselves and also doesn't do that for others.

• Being a self-proclaimed "sigma", "alpha" or whatever. Again, insecurity and toxic masculinity. Besides, real "sigmas" and "alphas" don't need to tell they're one. They emanate it by their confidence, kindness and compassion towards others.

• Dismissing science, eg. being an antivaxxer. You're setting up people for abuse that way, as it hurts peoples' health, and spreads harmful falsehoods.

• Only caring about sex. I'm a friend/partner, not your prospective fucktoy.
