It's really a question of understanding one's capacities and limitations.
Sure, on a personal level though, how sure can we be of those things really?
I can see the observation that places are full of people who wouldn't be one's first choice to hang out with, that's (like I said for me) kind of a given in interacting with groups and organizations..most irritate the hell out of me..but really, that is not just on them right..isn't that how we are supposed to approach it? What I find a little more questionable is the idea that it is only this way, or that this reality is a good reason to avoid it entirely.
It just seems like a misanthropic attitude that conflicts a bit with developing even a "fake it till ya make it" level of altruism, which I gonna go out on a limb is something we probably all have in common at least somewhat, trying to create a more open heart hopefully...
On the other hand, if one already
deals with this kind of nonsense at work, etc..I can see that in Dharma practice it would get insanely tiring trying to cope with the same stuff.
Anyway, it seems so easy to access Dharma teachings online now, much like many other aspects of social interaction, I have to wonder if it's a very healthy trend to have people simply believing they no longer need alot of two way interaction with others in terms of Dharma practice.
