Is an eerie similarity between two online groups of people going to mean you abandon attempts to bring about equality of the sexes, races, classes, etc.?
And if you will abandon it, what will you embrace instead? Conservative racism?
I get that maybe there are similarities but there are so many more differences between the two groups that it's ridiculous that people resonate with this comment. One group is "witch-hunting" to root out people who might be bringing stereotypes or prejudice along with their thoughts and ideas, the other is trying to root out people who are of a different race / nationality without even ever hearing any words from them at all.
Clearly one is better than the other, even if both have some similar flaws.
