Homosexual activists have stated numerous times that the reason they want same sex marriage is to change society. It’s for dominance. So the tax credit thingie doesn’t matter.
Furthermore, govts have recognized marriage for legal and social cohesion matters, establishing legal paternity and so on, and has for millenia.
Third, income tax in itself should be abolished and the entire marriage credit crap would be finito. Gov needs to stop doing about 50% of what it does (for a start) so it’s insatiable lust for our money would be a thing of the past.
The whole situation is rotten and it will not be fixed but only made worse by the gov not legally recognizing legitimate marriage. Legal marriage protects the children of the marriage as well.
It is not about “love” and/or sex but power. The kind of power that would force us all not to question the morality of their actions.
