Is a lack of success with girls/sexuality a major cause for mass shootings?

The shooting of this sort of type in New York has me convinced that it is due to a lack of attention from the parents, and this is one way to get attention.

Everyone: Racism, Sexism, Poverty, etc

PSOL: lol my parents don't pay attention to me so I have to murder 10 people lol

For middle class white kids, apparently yes

Mass shootings and “incel”-ism are symptoms of the same disease.  Both of these are very antisocial behaviors

Was going to say something along these lines. People who commit acts of mass violence are wired to be seriously at odds with the society around them, and that doesn't translate well into forming good connections with other people (whether that be one's parents, friends, prospective partners or employers, or anything else one can think of).

The question is why don't they have a good relation with the society around them, and what drives them to do such a high-profile crime like this.
