Which we should see as an excellent radicalization and growth opportunity!
It can be exhausting explaining ourselves again and again, always met with the same accusations and assumptions born from the mythos spun by our enemies.
However, we must remember these people are people, and many people change their minds given enough information, delivered with firm respect. For every belligerent person who appears like they wouldn't change their mind for anything, there are 10 people quietly lurking who are more on-the-fence. Even those who regurgitate insults and contempt may change their mind when the stars align!
These people are not our enemies, they are victims to the greatest campaign of dishonesty in human history! It is our duty to draw out the poison and deliver the medicine!
I know many comrades here have very difficult lives and do not have the patience or energy to deal with such people. Please do not exhaust yourself interacting with liberals, and allow comrades with more energy to deal with them.
Radicalizing online is not the end-all be-all, but at this point in the psychological war for those within the Anglosphere, every victory is invaluable!!!
When you say "both sides" what you mean is "the same con artist wearing a new disguise."
The "both sides" of capitalist, liberal "democracy" both work on behalf of the rich, not the people. That's why you've felt cheated by both, because both will work against you.
Being aware of your own shortcomings is good though, it's always important to question whether you have been fooled or not. That's why us filthy dirty commies practice "self-crit" or "self-criticism" where we examine our ideas and try to challenge them scientifically, similar to peer review. Of course, we could still be wrong, but we can at least manage to be "less wrong" that way.
