Judging the merits of anything by the title attached to it by its supporters is foolish. Titles/labels are often meaningless absent context. Otherwise, we all would have supported the "Inflation Reduction Act", because after all, who could possibly be against reducing inflation?
The only definite meaning I can attach to "MAGA" is preferring Trump to any other candidate. And I'm not even sure that is correct anymore, so I'm not exactly sure what it means.
Well it came originally with a well-defined agenda so it does actually mean something specific.
