"So I have to tolerate JC's outright, provable lies?"

Bruce - well.. why not at least try...
Experienced reasonable debaters can challenge the veracity of an opponent's claims
without resorting to shouting insults of "LIAR!!!"..
and kicking off a bar room brawl...

What we lack here is a barman with a baseball bat quick to nip disagreeable situations in the bud..
allowing other patrons to continue socialising peaceably...

Rather than Cops called and storming in to permanently close down the establishment...
