I'd argue (with no malice) that there's just as big a problem, if not a bigger problem, on the opposite end of the spectrum, where having any reaction at all to one's self or others being insulted, attacked, or mocked will draw hateful calls of "snowflake", "safe space", etc. Even the president mocks and insults individuals who haven't done anything to deserve it, which is a pretty dramatic problem. People might disagree on which side has the "bigger" problem, but they both do have big problems, and communication will always be absolutely impossible as long as those problem attitudes remain so common.
