You are right!

Your post makes sense. Don't argue with those that don't deserve it; time should be on your side.
总死亡人数是两千六百, sounds surprised to me! Many people estimate around 300-400.

At one hospital near 六部口 on June 5th, 1989, I saw the death-list occupy 2 blackboards, around 60-80 names, and some nameless dead people lying in the internal bicycle parking room waiting to be identified; before I see your post, I guess there are at most 400 death, now it is 两千六百, sigh!
