Here’s the difference, at least for me:
There are relatively few conservatives in Hollywood willing to speak up on political issues. I remember reading or hearing somewhere that there are a lot of people in Hollywood who lean right but won’t speak out on political issues for fear of being black-balled by the industry.
Meanwhile, liberals can speak out without any fear and they do so in droves.
If more conservatives would speak up, the left would all be “howling” for them to shut up too. If there were fewer liberals speaking up, the right probably wouldn’t give them much thought.
