Are they exactly the same in every possible way? No. Are they comparable? Of course. The liberal progress of human-kind, or at least the United States, has given the gay movement the privilege of not being quite as vehemently resisted as the African American Civil Rights Movement, but in some cases, very close. Nearly all aspects of the black rights struggle can be found in this movement. Similarities include oppression of rights (yes, the ability to marry the person of your choosing is a RIGHT), tactics of protest, violence, discrimination, etc. I would simply consider the gay rights movement slightly less extreme
