So what? Why do you need to conform to a socially constructed persona?
Being an activist and doing things to further causes you believe in, when those things are predictably going to anger those in power, means you are trying to do an adult's job. And that means you have to be an adult. That's not a "socially constructed persona"; that's a fact of life. You can't be a "boyish intellectual" and take on the establishment.
On the other hand if you have a social anxiety you probably need some kind of stronger help to be able to function.
Either way the alternative of avoiding much of the world and relying on oehters to get by probably isn't preferable.
