this is an imporant word, and we should be paying attention

What this means is "When it cost us (our tribe) nothing, the suppression of right-wing speech was okay. Now it's costing me and our tribe something, it is no longer worth it." We cannot wait until each leftist feels their speech eroded for them to come out in favor of free speech. This is an entirely self-serving statement. Do not confuse this for having principles, if ContraPoints was immune to censorship, she would not be saying anything at all. Leftists do not have values or principles, and only operate on friend-enemy distinction.
