...if somebody says on the internet that they don't like blacks because of XYZ, then shoots a black and claims self defense, he will still have a tough time in the social court, but by law there is a lack of premeditation...
No, that is really not correct.
Things like premeditation, intent, justification, etc., if the matter is in trial, will not be decided as matters of law. They will be decided by the trier of fact (i. e., the jury if it's a jury trial) as matters of fact based on all evidence presented. And we've been discussing the various factors, from the defendant's haircut to the embellishments on his gun, which can color a juror's perception and evaluation of that evidence.
The only times a matter, like the question of premeditation, might be decided by the judge as a matter of law would be when there is no evidence on one side of the question so that the fact can not really be in dispute.

...supported fact: this bullet was fired from this gun.
unsupported fact: this man fired this gun 'out of anger and hate'...
Nope. If whether the defendant acted "out or anger or hate" is at issue, there will be evidence to support the inference.

...depends on if your town is full of people easily duped. some locales have educated people, logic and reason determine most things for them. others have rather simple minded folks who are governed by emotion more than anything else....
Also wrong. Pretty much everywhere will be populated by a wide range of people -- some educated, some less so, some prejudiced and some broadminded. Any jury will be made up of folks remaining after those challenged for cause (objectively unsuitable) and those eliminated by each side as the least desirable to its interests (up to the limits of each side's respective peremptory challenges).
