I think it would be a big step forward if republicans used actually free social media platforms rather than those that are controlled by their leaders and heavily used for propaganda.

Good idea. All parties should do the same thing. Any party that only sticks to platforms used for propaganda and echo chambers is a problem. People need to think for themselves, form their own opinions, and stop treating party lines like religious doctrine. Regardless of what side of the aisle they are on. Information is power.
