^ um okay, I wouldn’t really go that route, breaking their toys and stomping on them, a bit extreme IMO 
chips I think I remember that thread too, I don’t really remember it saying that the people who cant stand kids to visit them do not deserve to be parents, 'cause that’s really wrong.I do remember it saying that visiting other people who have kids is a bit more comfortable and easier than visiting people with no kids, as they don’t really get it …yet. (as was obvious from a couple of responses)
ANywayy, X2, we’ve had some family friends whose kids were like that.I remember hinting to the mother a couple of times, as the main issue was him hitting and bullying my son, but there was no response whatsoever. I even tried telling the kid a couple of times how ‘We dont hit’ or ‘We share’ etc etc, but…yeah..
So we totally backed off,started visiting and socializing with them less and less, as it would usually turn into an really uncomfortable situation, especially for my husband who could not stand their indifferent attitude. Sometimes thats just better, I guess, than to let the issue get between adults (as obviously no one appreciates their kids being disciplined by others.)
