Except I don't complain about people having a different opinion than me, AOG. I'm not shy of calling some opinions stupid if I think they are so, but unless they're about intervening or controlling my own life* I'm not irritated by the fact that they exist.
Despite the fact that we have a right-wing government, the British press is predominantly right-wing, and the US president is far-right, you and other right-wingers still seem determined to believe in the vague idea that there is some kind of sinister liberal cabal influencing society for the worse.
Yeah, celebrities tend to have a liberal bias because the entertainment industry as a whole tends to. This is not news. It also doesn't make a lick of difference. But you still seem to have some kind of problem with it. The tone of your question heavily implies that this is illegitimate or somehow suspicious. I don't understand what your problem is, except for the fact that there are some celebrities who have opinions that aren't yours.
*For example, people telling me I shouldn't be able to marry if I want to, that my lifestyle should be illegal, that it's "inappropriate" for me to show any sign of affection to my partner in public.
