I've only been playing Tabletops for about a month now, I didn't realize people had such strong opinions on DnD systems. I've only ever played 5e.
We're talking about 50yrs of gaming history, since people started playing in about 1974. And, yes, I've met people who've played for all that
fifty years, invested many thousands of hours in the hobby (do the sums on '25hrs a week, 50wks a year').
Some of them... hold strong opinions.
DnD... gives you a playable game, in a reasonably fun (sometimes very nasty) fantasy world. This is the case from Original DnD through to DnD Beyond, or whatever the latest version is called. But, important to realise, it
has its limitations. But, so do all the other table-top or computer-moderated (role-playing) games.
Make sure your Suspenders Of Disbelief +3 are kept in good order.
EDIT:
*sigh* I should know better, but...
Some people swear by one or other version of
Hero System, which from 4thEd was fully multi-genre, arguably in a more thorough and better way than the d20 games that came from the DnD3rdEd SRD.
But. While people converted DnD campaigns to it, and ran cross-genre games, sometimes spread across multiple multiverses, it has
quite clear weaknesses. That, if you talk about in the wrong company, may make you feel as though mobs with torches and pitchforks might be in your near future.
So. Respect people's culturals. You know it makes sense.
