We've been shouted down with "fake news," "alt-right," "conspiracy theorist," etc.
How about a challenge: MSM, and MSM loyalists, get to the heart of our claims. Acknowledge that pedophile rings exist. Report on them. Investigate them. Report on the odd amount of government officials convicted of pedophilia. Report on human trafficking in the US and across the world. This stuff is reported briefly, if ever. Stop blaming our concern on fake news and start acknowledging that there is cause for concern when it comes to these subjects.
Instead of positing walls of text in comment sections and social media, at least some of us should try this approach. Point out that maybe pizza gate wouldn't be a thing if people didn't feel the need to do their own investigating.
It won't result in an end to the fake news cover up, but it will make the media look guilty as fuck.
