Yeah, every tax break for a married couple is a financial burden on those of us who couldn't get that idealized tradsoc relationship. Getting married means you are participating, and benefiting from this persecution. Even legalizing gay marriage just legalizes more people to benefit from this persecution. Abolishing state sponsorship of marriage would be good enough, but that can't happen long as marriage exists, because its priests will just howl louder until they get their special treatment.
So we need like... child raising agreements that don't presume God's blessing, rather than expecting everyone who can't find their soulmate to pay double taxes.
