The statement,
they shouldn't be allowed to vote imo. only people with a basic understanding of economics, who know a bit about the candidates for whom they're voting and are at least 21 should vote.
contradicts
No one is saying that we shouldn't allow people with different views vote. You're straw manning.
The reason it is contradictory is that your basis for "basic understanding of economics" was that they don't believe in zero-sum economics. If someone believes in zero-sum economics, they would be barred from voting based on your standards. You also said later that "No one is saying that we shouldn't allow other people with different views to vote."
Therefore, you said that certain people with different views would be barred from voting and that nobody would be barred from voting.
Only one statement can be true, as the other would be false.
If zero-sum believers cannot vote, the statement that "No one is saying we shouldn't allow other people with different views to vote" is false as by your previous standards, you are saying that the opposite is true.
If you are saying that "no one is saying we shouldn't allow other people with different views to vote" is true, the statement that "zero-sum believers cannot vote" must be false because if the zero-sum statement is true, an exception to your "no one is saying" statement would exist and would be false.
Therefore, only one argument can be true.
Which argument is true?
