Just turn the ‘fact check’ card around on them when arguing with liberals online. When they post lies just say stuff like this:

Fact check: This post contains misleading information.

(Provide a logical summary why they are wrong)

+

(Insert quoted content inside quotation marks)

+

Provide abbreviated link (eg usa.gov) minus the www. or https:// or full url slug to avoid spam filters

It works quite well. Plus it makes a mockery of how Silicon Valley can think they can be arbitrars of truth.
