Also note that the proton is not an elementary particle so it is really a question of "are the various quarks really 1/3, 2/3 of an electron charge".
Crackpots have found thousands of formula that try to explain the ratio of the proton to electron mass but there is no expectation that there is a simple relationship between those masses since the proton mass is the sum of all sorts of terms.
Crackpots are downstream of the "physics community" awarding cultural cachet to certain types of questions -- those with affordances they don't necessarily "deserve"-- but not others.
(I use quotes because those are emergent concepts)
Same as "hacker community" deciding that AI is worth FOMO'ing about
