1) thats not true
2) circumstances change
3) why should you have to vote in person? several states were already mostly mail ballot even before covid.
4) even if I'm ok to vote in person, voting by mail makes it safer and smoother for other people by lowering density at the polls
5) voting shouldn't be some gauntlet that you have to overcome and the winners get to participate in democracy
There is a big difference between absentee ballots and universal mail-in voting.
No one (that I'm aware of) has a problem with absentee ballots for people who are uncomfortable voting in person.
The problem is with the universal mail-in voting.
When someone applies for an absentee ballot, there are human eyes checking the data to make sure it's the right person and that they are eligible to vote in that state at the time. (as was caught in Florida, when someone applied for his deceased wife)
But, with universal mail-in voting, there have already been numerous cases of ballots that were sent for people that don't live in that state anymore and for those no longer among the living just within our own communities, and probably a whole lot more across the states.
