I think the more direct route that incels partake in paying Chad to fuck Stacy is pornography consumption.
Your taxes are always going to go towards a tonne of shit that you disagree with. That is simply part of working. You can become an MRA or conservative activist if you're tired of the "social justice" trope and abortions.
However, a more direct route you can take to stop paying Chad and Tyrone is to stop watching porn, including "free porn". Free porn sites like pornhub rely on ad revenue to continue their operations.
In 2018, Pornhub made $426 million in revenue from ad sales. This money funnels down into the pockets of Chad, Tyrone, Stacy, Sakura, Isabella, etc.
I stopped watching porn and switched to vintage Playboy magazines. I started a small collection. No funds go to Chad and Tyrone. Not bad at all.
