I was primarily referring to online-activism, but agree with your broader view. I said this a few days ago[1] that I'll be voting for anyone that opposes strong ideological political motifs. If one can't defend their stance with reason and civilized discourse, then I am automatically turned off from that ideology. It's gotta stand the test of debate, science, truth, generally accepted morals, justice and fairness. Mob thinking, poor reasoning and supression needs to be called out and exposed (not supressed).
