Interesting question for me, especially given the definition of "celebrity" in today's world is so, shall we say, generalized. Who/what exactly is a celebrity?
To answer your question though
@Tight_N_Juicy, I don't care for "celebrities" who use their expression of opinion to simply try to stay current in the spotlight/press. Who otherwise couldn't get attention without saying/doing something outrageous or stupid that garners attention. But I also get that for some, any attention is good publicity. Gotta stay current in the peeps minds. Even when they end up looking real stoopid!
And I don't want to hear opinions from anyone for that matter that's not well thought out, steeped in some type of factual reality. Not some conspiracy. That can't be verified. And I don't care to hear about how anti- someone is; I'd rather hear why one is pro- whatever it is they are opining about.
For example, if a "celebrity" is pro- or anti-Trump, tell me why. Why are you for what it is you are for. Tell me that. Give me some specifics that caused you to have that opinion. You just might get me to pay attention.
Conversely, if your opinion is based on being for someone/something because you don't like the alternative, that's bullshit. If one states an opinion, be man or woman enough to justify your position. Otherwise, STFU. I'm gonna ignore the hell out of you. Kinda like I do (for the most part, lol) certain posters in the Politics Section here. You believe it? Support your belief with facts. Give me something concrete that I can research and learn about that I may be ignorant about. You know, reality. And nothing I detest more than conversing/debating/arguing with a closed mind.
And for goodness sakes, please practice what you preach. If you are on one side of an opinion/movement, don't let me hear that you're guilty of what it is you are railing against. That's when I'm not gonna ever listen to another thing you may say. Regardless of whether or not I may agree. Cuz I got nothing for a hypocrite. Except contempt.
