Why are we letting someone openly endorse a massacre here?
Because others were silenced for similar reasons.
So, what you are saying is "well, it's a shame Tiananmen Square happened, but since the Communist Party had them run down with tanks, we might as well do the same in solidarity with those who were killed." That makes no sense. If you want to support the protestors who were killed, you should start by supporting everyone's human right to free speech, no matter how disagreeable it is.
I might have misread your post once again (why do I always misread your posts in particular? It seems that always happen when we engage in a debate), but do you mean the protestors, or do you mean those who have, as you see it, "endorse massacres" in the past?
