Homosexuality is one of the most egregious sins against God. Evading taxation from an oppressive government isn't even on the radar screen.
Lying and bearing false witness in order to do it are. Trying to twist it, to convince God you aren't lying by using a Thesaurus isn't good for your soul, God is impossible to fool.
You try to tell me you are a hero, while you describe something that for most Christians means certain damnation. You should talk to your pastor, and if he's the one giving you this "advice" you may want to reconsider the true source of his "inspiration"... No pastor would lead his flock into lying and bearing false witness.
Protest taxes as you will, but don't lie and falsely claim that you are not perjuring yourself by signing the documents with lies on them.
