I'm a hard-core liberal progressive definitely. Or perhaps I'm a progressive liberal. Anyway, I'm one or the other unless I'm both. Conservative ideology in my view is morally and intellectually bankrupt.
Back in the last century, my somewhat more moderate - but still definitely liberal - father and my teenage self debated this. When the argument heated up, he would put his hand on my shoulder and say “my son, surtout pas trop de zèle.” Okay, maybe he didn't always say “surtout pas trop de zèle” but I'm pretty sure he did at least one time. And if he didn't he should have.
