Thanks for a reply. I did take a look at your post but I don't think it really engages with the points that I make (it engages with arguments that are perhaps superficially similar but importantly distinct)

In general a PUA should always make a woman feel good, otherwise why should she choose to stay with him? Probably women suffer much more through awkward interactions, stalkers, etc...

I have no problems with certain things that one might describe as pick up artistry. My comments are reserved for the things that don't involve respect for a woman's welfare (demeaning her, for example). And yes, I'm sure people suffer more through stalkers but that doesn't set the bar very high.

Making a woman feel insecure might work, so does a movie that makes people feel scared(ever enjoyed a good horror movie?). Should we blame a PUA if that works for him?

If you think that people should care about the welfare of others then yes. I think here we have identified the ultimate source of our disagreement. The fact that you think this is even a question worth asking shows that we have substantially different background assumptions (and this perhaps explains why you find attacks on PU confusing).

ETA: I realise now that it was unclear whether you were asking whether we should blame a PUA for the movie thing or for deliberately making a woman feel insecure. If the first, no (except perhaps in unusual circumstances) as going to a movie doesn't go against the woman's welfare presuming she, like many people, finds the fear of a horror movie desirable or finds it to be made up for by other aspects of the movie. If the second, then as per above: yes, I think a person should care about the welfare of the person that they're picking up.
