We've been past that point for at least 2 years.
While it's understandable that this is the hill Trump is choosing to die on, it's still a weird ass hill to die on. He should drop it. I understand he is pro-vaxx, anti-mandate, and he kinda has to be, but he would do better if he didn't counterattack here. He has to cuz you can't teach an old dog new tricks, but if anyone else is a legitimate(read non establishment puppet)option on the right people will vote for them over Trump.
Imagine you're a dem or a lefty or a normie. You have been told(or coerced) for 2+ years to take the shot to keep yourself healthy, grandma healthy, society can go back to normal, stop the spread, prevent death, be a good and moral person.
And you believed them. You still do believe them because these are the good people who are inclusive and on the right side of history. The adults in the room.
Now they tell you those bigots, those idiot science denying rednecks(who are racist and homophobes btw) who have been saying for 2+ years not to take the shot because it can/will cause you bodily harm, were correct despite them already telling you the last 2+ years that those idiot bigots were science denying idiots.
Do you think it will matter to you at all if they attach that to "Trump did it"?
