If there’s no sexist law that says men should hold doors for women and to let them go first  then why are men expected to do those things?

I'm a woman and I hold doors open for people all the time.   It's just the polite thing to do regardless of what's in your underpants. 

I hold the door for broads until they get real close then let the door slam in their face. Some broads will see you holding the door then slow up and start prance walking thinking they the **** when they smell like ****.

Don't do if you don't want to

If that works in your life, fine.  Just don't keep posting that no one will date you.  I'm in a male dominated profession.  I open my own doors.

Need to be herded in correctional facilities

There is no expectation these days because thanks to people like you, courtesy is almost nonexistent. 

I hold doors, after a moments scientific study. The problem is, my study results show, most of you are not nice people. 

So crows the incel who couldn't get a date even if he paid for it.
