Lot to touch on here. Not going to get to all of it. First off most people do cheat according to an overwhelming majority of surveys done over the years. That’s not including those who lie on those surveys.
Secondly the point is when normal people cheat, it doesn’t get blasted/they don’t get blasted by anyone outside of people related to them or their situation. As it should be.
Thirdly and finally, the entire point, since you seemed to miss it entirely, was that this is tabloid shit. People should have better things to talk about than which celebrity cheated, especially since the future of our nation is potentially in jeopardy, and a debate related to that future just occurred. But by all means spend your time making a big deal about Dave cheating.
And as for making the announcement himself? That’s him owning it as far as I’m concerned. Which is what I did when I made that mistake. Doesn’t give people the right to talk down on him for a mistake literally half the world makes once or more in their lives.
