What I'm enjoying about this thread is that as we 'drift', we keep coming back to thinking about boundaries. I don't have a huge problem w. the violation of boundaries---it's a normal part of the human condition, particularly since 'boundaries' by definition are flexible and easily penetrated.

All we can do is state our own boundaries and call people on it when you feel they are violating them (whether it's through polite and seemingly reasonable conversation that expresses opinions that we feel disrespect certain people (violating their boundaries) or whether it's a violation of 'style'..i.e. swearing, calling people names, adults acting like 6 year olds, etc.)
