And I don't understand how its irony please explain.
By definition, anyone who makes a specific effort NOT to conform is conforming. He or she is just conforming to a different standard than the one he or she is trying not to conform too.
Conforming to an alternative life style is still being a conformist. In fact, non-conformists are one of the biggest groups of conformists in the US.
Hence, Irony.
Edit: it IS possible to not "conform" because conforming doesn't mean doing things that other people do. It means INTENTIONALLY doing things that other people do BECAUSE other people do them. The only way to NOT conform is to not TRY to conform or to not try NOT to conform. Much like Zen budhism says. If you WANT to obtain enlightenment then you CANNOT obtain enlightenment, because that desire will prevent it. The only way to obtain enlightenment is by clearing yourself of ALL desire.
Edit Edit: Ohm. Ohm. Ohm.
