I sympathize with a lot of your points but this is what you're doing ITT:

• Make the most toxic person in the world your party leader
• His example encourages your voters to spread unprecedented amounts of hostility and lies for 8 years
• Go on the internet and act super polite, as if you've done nothing wrong and the D's are all crazy for not being nice to you anymore

R's are never going to get any reconciliation until they at least admit to the shitstorm they've caused (and have just chosen to extend another 4 years). But I don't see that happening on a party level. All they do is very occasionally say something like "both sides are getting too heated, let's cool off a bit" which accepts no real responsibility and changes nothing.
