Meeting strangers in secluded parks for what is obviously sex of some kind IS deviant behavior
Ok, it's outside the norm. No one, again, is suggesting he wasn't a dick. Specificall you said his behavior was unethical.
the kind he counsels others to avoid
Uh, huh? Is he a sexual purity counselor? I wasn't aware that there were counselors that said "this type of consensual sex between adults is deviant and bad".
Strangers, sex, parks and seclusion don't mix for a healthy social environment.
For some, no, for some, yes. It's not nearly as deviant or uncommon as you think.
You can't be that dense.
We aren't. I am just asking where the ethics violation is. There was a vague mention of a college class you took, but that hasn't really shown anything.
