No....not at all.

Believe it or not, I can carry on a conversation about something trivial without having to interject politics about it all. Again- it's a dumb non-story and I, someone who is online enough, saw maybe 1-2 articles about it in my feed and went on by. It's not a big deal and regular people won't see it as a big deal either. Ie. this wedding is not something that at all is affecting their day to day life because it's a one off and will be forgotten in a week's time.

You'd have better luck convincing people that she is bad because her private jet burns so much fuel and releases so much CO2 into the air which is causing this insane heat and rapid weather changes, more tornadoes in areas they previously weren't in, etc. etc. Not downtalking and making up fantasies about a wedding (which, most people are far more likely to have a wedding of their own and attend many so maybe attacking the institution of marriage and the fun of a wedding is not the play.) You'd also have more luck saying we shouldn't be reliant on billionaire's generosity (like her donating to whatever cause, maybe wiping out medical debt or whatever she did) if we just taxed all billionaires so this was done all the time.

See what I mean? Catch more flies with honey.

I honestly equate this to some trekkie going up to a random person that goes on and on about how it's the best TV series ever- no one asked and they certainly aren't going to be super receptive. Talking to people and slowly convincing them of your position and the righteousness of it is a skill and a necessity, not some nice add-on.
