Pointing out silliness doesn't indicate insensitivity.
Calling something "silly" that may not impact you but could have a greater impact on others is insensitive. It so insensitive that you'd have to conceal your identify, or hide your opinion when not voicing your opinion on the Internet to avoid backlash and becoming untouchable to (some/more/most/all) employers. I don't understand the gain, other than dog whistling.
