Not sure this poll should be trusted, but what it at least shows is that more polls should be conducted. There is absolutely nothing surprising about this result.

Certainly many progressives won't be concerned, because they are more likely to think that suppression of wrongthink is good. Only politically incorrect varieties of prejudice and discrimination are bad.
