No, I'm generalizing over both using an analogy. If I believe in something you consider bad, I will be gleeful that you defend my right to say it as I consistently refuse to defend yours. I will be thoroughly satisfied that you've tied your hands with rational argument as I tear apart your standing and support through every irrational means available. Rational debate is how you decide which ideas are worth keeping. It is not how you kill the ones that aren't. (You've found that it works sometimes, but you should bet actual counter-actions work far more often.)
