with all due respect, it seems to me that your concern over the rancor and hostility here (of late) is misplaced; there is a lot more unanimity here when it comes to practical matters than when it comes to discussion topics.
It seems to me, just my observation, that the establishment types are angered and disgusted by anyone who won't back the party, simply because it is the party.
I absolutely hate what Democrats stand for.
I absolutely hate what Republicans won't stand for.
