So it would be cool for an anti-drug person to shoot up heroin on screen, or a devout atheist to play a preist? I get what you're saying it's just acting, but it's sad that someone is making a living off something they are against.
I would bet that most long-time actors played something in a role which they don't like/support in real life. If it's the role of a guy who likes illegal street races, the person who loves bank heists an does let them look cool, the role of a mother who has a dog even if she doesn't like them much in real life or the man who acts as happy janitor even if he always thought that's a job which can't be fun...
These are roles in fictional films, they don't have to be made only by people who are exactly like that in reality. Not the actors, not of the writers and producers and not anyone involved in most projects. I would be pretty scared if books of some writers would represent how they are if they could only write what they support without getting called hypocrites.
But when politics are involved and legislation of laws, you have to have certain credentialts and make actions that support your brand of thought and what changes you would like to see in society!
just as I would find it disturbing if politicians honestly admitted to loving house of cards, or reading bullshit books like 48 laws of power, which one I know who is politically involved has been doing... And I find people like that being put in charge fucked up.
if you wanna talk politics and change, always be an example of what you wanna change... These are laws that will change millions of lives, so being wishy washy about principles is naturally seen as hypocritical.
