i think the reason why a lot of us are suggesting "get rid" as first option, is when you're having a discussion with a PA man they're so weak and sensitive to criticism, its not even a conversation?
lornas thoughts :"how can we move this forward, i'll genuinely state what i think and feel?"
PA person thoughts: "oh my god I'M being criticised and not getting approval! i need to WIN here."
It matters more to them that they protect this incredibly fragile self image in which they are "king of the situation" than actually resolving the issue?
So they just produce weird uber defensive "straw man" arguments where they're not actually addressing the point?
Or try and enlist sympathy for themselves - get others involved in supporting them?
Or its "someone" else's fault - yeah its those crazy feminists or my boss or God or something 
Or claim they're "just being honest" or "it's how they are, its masculine logic".
if you walk away cause they're so fucking tedious/defensive you're thinking of shagging the milkman, then they'll do a little victory dance cause that means they've "won". No love, you're just pathetic and others are bored with you.
So: the outcome of a discussion with a PA man: either you can go down to "his" weird game playing level, or leave/rid.
funnily enough when one meets men who are genuinely masculine with a sense of self they take responsibility for their opinions and their actions, they don't describe themselves as "typical blokes" to avoid criticism!
(that seems to be used by whiny self involved types who don't actually like anything resembling manning up)
