I've made a theory about why women find men with ASD creepy
Men with ASD tend to have higher glutamate levels which affects their capability of learning social cues. Too much glutamate has a negative affect on neuroplasticity. Women can see that these men have low capability to read body language and thus these men become "creepy." Even if the guy is just existing and not bothering women in any way, women think that a guy who can't read non-verbal communication is a possible threat. Most men can after all read body language and tell "yeah, this woman isn't interested" meanwhile a sperg may not be able to do this. Hence why women pre-reject you by calling you a creep.
Of course this is only a problem, if the said man is unattractive. If he was attractive then women wouldn't find him creepy
Also ASD reeks of low social status. Of course women want nothing to do with any man who is bottom of the barrel in social status
