Man, where did this notion that, in order to stay "political correct", you should avoid discussing any topic that can potentially offend people.
How do you expect a democracy to work if everyone is going to just stay in their own mindless bubble, feeding from their own echo chamber of pre-approved knowledge, without anyone ever challenging their world view? Are you really going to base your choice of who's gonna lead us on whatever tabloid soundbites sound good to you, while ignoring everything else?
Last I checked, a democracy is supposed to be a governing form of a government chosen BY the people, FOR the people. And the people is -everyone-, not just whoever you think is looking nicest on TV in that one interview who maybe said something you thought sounded close to smart, so you'll put your entire future in their hands.
If you don't think regular people, celebrities, whatever should be able to talk about politics, I'm afraid you don't deserve a democracy. You want a dictatorship where only POWER is important.
And if you attack people for having political views, to the point where they feel harassed, you're an asshole. Plain and simple.
