The reason is quite rational. Reminding you any an unfortunate soul who comes across this website what an irrational hypocrite you are. Otherwise they might just think there is something like a point in trying to explain your endless misconceptions or point out the many contradictions you advance.[IWRA] You’re the hypocrite.
Yet somehow it's always me with the links to the posts proving hypocrisy and never you or the other zombies.
[IWRA] You support a moron like Trump to be President when he is the epitome of personal attacks.
A hypocrite is someone who doesn't follow the rules of behavior they proclaim for others. If I said Trump is flawless then I would be proclaiming that everything he does in accordance to my rules. But I don't therefore I am not a hypocrite no matter what Trump does.
In the extreme case: "If Hitler invaded Hell, I would make at least a favourable reference of the Devil in the House of Commons." = supporting someone politically is not endorsing them morally
Even Trump hasn't blurted out "what about your dead mother loser" because he was losing a debate (I've never seen him debate but that's besides the point).
