I've been seeing a lot of laughing over the ridiculousness of Antifa and Black Lives Matter being considered just an 'idea' by the left. You're all correct in your sentiments for laughing, because it is ridiculous. Antifa and Black Lives Matter are far more than ideas -- they are highly organized groups working in unison for an ulterior political agenda.
However, one comment that stuck out to me was where someone here on this site said (paraphrasing) 'Given that Antifa is burning down businesses, I guess that must make Antifa a pretty dangerous idea.'
This is how the left wants to shift the overton window. They want to conflate ideas with organization so that they can weaponize the obfuscated differences against conservatives and the 1st Amendment agenda. If they can get more conversations started to that effect, even if they're done mockingly or in jest, it has an effect on the universal perception of how people interpret ideas with regard to the actions by organized groups.
It starts with us mocking Antifa being considered just an 'idea' in Portland. From there, the Left may try to use our mockery as the foundation for conflating the support of Trump or Conservative values with something inflammatory or irreconcilable (like, say, white supremacy).
Be mindful of your language and the words that you speak. I fear that there are forces who are playing upon the connotations.
The answer is because the rioters are fucking communists. The DAs aren't charging them because they're also communists. Reminder that this shit has only happened in DEMOCRAT STATES/CITIES.
If dipshits on the internet/in real life try to tell you that the riots are because of REPUBLICANS, ask them why DEMOCRAT DISTRICT ATTORNEYS in DEMOCRAT CITIES with DEMOCRAT MAYORS AND GOVERNORS aren't mobilizing the state police OR prosecuting these rioters for violent crimes.
