Nope. That’s another fail.
You can’t call an obvious attempt to suppress speech by some pretty sounding term like “common courtesy” and expect to get away with it. Not here anyway.
This is just another leftist tactic: “While you are free to disagree with me or criticize, if you do so it only proves that you are a discourteous heathen.”
You seem to be seriously inclined to leftist tactics.
You will be called out here on FR every time you try to restrict speech. That’s one of the primary mission objectives of Free Republic-to zealously protect free speech. So quit it.
