Is our own innate phobia an obstacle to us being truly happy?

I recently read an article whereby 'Gay' people are now going to a and Gay therapist to be cured of internalised phobia rather than going to a hetroual therapist to be cured of ity. Is this really an obstacle to true happiness our 'innate' phobia stemming from living in an environment where we are constantly told ity is wrong, abnormal or somehow something that needs to be cured?
