Jay Bhattacharya, said here that I don’t think anyone disputes that it increases the rate of myocarditis, especially in young men..

Likely he is referring to this study that:-

The risk of myocarditis after vaccination is higher in younger men, particularly after a second dose of the mRNA-1273 vaccine

But this statement is about a particular (temporary) adverse reaction. It does not mean the vaccine is net more harmful. The fact you came away with that impression just shows how easy it is to misrepresent facts.
