"Raising awareness"? What about all the LGBT people who were disowned by family? What about people who were beaten up and sometimes killed? What about the decades of marches (and initially, riots) for this. What about people who risked their jobs, their home, their family, their neighbourhood or violence from the police all for their cause?
The LGBT rights movement was hardly slacktivist 'awareness raising'. It was real struggle with real costs which is generating real results.
The struggle isn't over yet. But over the last 50 years things have gotten better. To give an example, the UK has gone from "Homosexuality should be illegal" to a conversative tory prime minister saying "I support same sex marriage because it makes marriage stronger"
