Bigotry begins when you force your idea that “same sex marriage is one of many wrongs” onto others.
It’s fine that you have your beliefs. Your beliefs are yours.
It’s really rather simple. Keep your beliefs to yourself and do not force others to act on or become a part of your belief system by enshrining them into law, etc.
For instance, I believe that people who force their beliefs, esp. religious, onto others should be taken outside and beaten to within an inch of their lives and then deported to Saudi Arabia with a blaring loudspeaker announcing their beliefs that Jesus is Lord and Savior and Muhammad is a pedophile and that Islam is apostasy hanging around their necks.
That would bring me great joy.
Beheadings are scheduled every Friday on Jami Square.
However, I would never act on that belief nor would I demand that it be codified into law.
