Response:
1) Like you said in your follow-up, there is a tznius problem. Additionally playing pool is not an activity engaged in by a Ben Torah/Bas Yisroel.
2) Not tznius to talk to a female (non-family) about her clothes.
3) Opening door for your female date is a pure liberal American shtus. This “chivalry” business has no basis in Yiddishkeit.
4) Germs (and doesn’t pas for a Ben Torah/Bas Yisroel)
5) I misunderstood your point. I take no position.
Certain elements will call me a “fanatic.” I’ll happily take my punches for whats right.
