I kind of agree with this. And, thankfully most of us in this country still have a choice on the matter. Those who don't, likely didn't have a choice on the other vaccinations they've received due to their jobs or whatever prior to COVID - albeit that's often brushed under the rug in this discussion (hi, military guys).
The one thing that really bugs me about this though, is that many of these people want to have their cake and eat it too. If you want the choice to get vaccinated or not, you need to recognize that choice comes with its own set of potential consequences, as it always has. You are free to homeschool, and not go and attend or work at places that require it, as you always have been. These things are not new.
I really just long for the days where we can all once again agree that the anti-vaxxers are just as nuts as the flat-earthers, but instead we have people dying preventable deaths in some insane attempt to prove a point.

In regards to air filters in trucks, as someone who really enjoys a clean interior, I want my filter to do the best it can. However, I'm not so sure how much I care about it killing bacteria and viruses really. I can't imagine, even running the HVAC at 100% power in recirc, the truck is going to be actively cleaning the air well enough to make any difference for me. End of the day though, I suppose even if it does things 1% better than not, that's a 1% improvement.
