Then techsupporter said something like "actually, booting them off does work".

Finally, paraphrasing your comment, "so you're saying you should let private companies decide?" No, that is clearly not what techsupporter's comment meant.

It's ok to disagree with the second half of that first comment ("booting them off doesn't work") without expressing an opinion on the first half. In fact the way the original comment ties together those two things has has led to the quagmire of crossed arguments you're seeing in these comments, so untying them is quite important.

If someone wanted to post about how much they hate a certain race, do you believe the moderators here have an obligation to allow that post to remain?
