Let me translate your comment with equivalent wording that reveals it's true nature.
Imagine being caught calling for the eradication of jews in private and then being fired and called an anti-semite for the rest of your life. Even though you didn't bring this into your workplace and then companies being reluctant to hire you.
also your drug criminalization is an entire load of false equivalence bollocks, drug criminalization is a far more complex issue than Gay Marriage, or rather whether we should treat people equally. There are very valid arguments for certain drugs to be criminalized that are way too easy to abuse and kill people with, like fentanyl and I say that as someone that's a supporter of full drug decriminalization.
Not to mention there are levels to drug criminalization, there is a difference if you have a gram of drug on you or a metric fuck ton.
There is no version of treating LGBT+ as just somewhat less equal that's morally defensible.
