That is the reality of things. The rules are artifices so not everyone plays by them.
The kind of questioning we commonly see now biases political thinking, belittles Human dignity, trivialises serious issues, and, ultimately, discredits the entire political process. That is affecting other people, specifically the entire body politic, and for that reason, if nothing else, it should be opposed.
Having seen some political writings from previous centuries I don't think that is anything new. I take the risk of presuming that anyone who values truth would oppose intellectual dishonesty in politics and media.
Oh I'm quite sure you're right. Doesn't mean it shouldnt be opposed though.
The impression I get from history is that these things are cyclical in nature. We go through periods where reason, rationality and logic rule debates, and then it oscillates back to emotion and insult and abuse. We seem to be living in an age where we are racing to the bottom, as your tagline implies.
