What is the issue with Free Masons and Free Masonry?

To me it seems like it’s mostly a secret society for Men to discuss ideas and get connections.

To me the conspiracies between free masonry sound very similar to the conspiracies about Jesuits controlling everything.

I remember watching a documentary based in Italy during the Modern Era that the Mafia and the State uses Free Masons groups as a middle channel to talk to each other not in public.
