You don't need to be.
I've been trying to popularise this amongst the left (actual left not synthetic left ie. those that demand as the lowest bar for "being left" the absolute and complete destruction of Western imperialism and Western capitalism. Not the synthetic left labour aristocrats that try to "both sides" shit when it comes to Russia/China/Iran/INSERT_WESTS_ENEMY_IT_WANTS_BALKANISE_AND_DESTORY_FOR_NEW_MARKETS)
Is that we should all be learning from conservatives and particularly Roger Stone
Who's philosophy is Never defend, Attack, Attack, Attack
Some cuckold brings up the wildly discredited black book of communism "100 million dead under gommies" bring up the fact that British capitalism is responsible for 1.8 billion indian deaths alone so surely 100 million dead from every communist country in the 20th century is a million times better than 1 capitalist nation? If they change tact point out under the metrics of that defined "100 million dead" India achieves that every 20 years
Another cuckold brings up Xinjiang (a recent topic) point out that the US has starved 27 million Yeminis in a completely manmade famine which is over double the population of Xinjiang so why don't they shut their fucking mouth and focus on a problem they can at least pressure their government about.
They bring up the falsified "slaves picking cotton in Xinjiang" (an obviously emotionally charged call to USsians with US particular history) point out how come they have no problem with slave children farming chocolate in the Ivory Coast , the fact that Burmese slaves are pumped full of amphetamines and tied to the prows of boats and pulled apart if they disobey orders or how come they have no problem with the child slaves of the Congo mining coltan for their mobile phones and laptops?
Bring up the fact that only 2 years the US army was bombing the Uyghurs in the East Turkestan Islamic Movement which the US designated as terrorists up until this year
You can adjust your honesty, disingenuous, vitriol and disgust at liberals and conservatives with depending on how dishonest and disingenuous they're being but leftists should understand that even the "well meaning liberals" that at least pretend to be based in reality are in fact disingenuous, disgusting gaslighting pieces of shit and you should have no moral qualm about being as disingenuous, flexible with reality or gaslighting in return.
In for a penny out for a pound
These lib and conservative disgusting pieces of shit that now pretend to care about muslim lives in Xinjiang (definitely the human rights they care about and not the geopolitical rivalry opening up between West and China) remind them that they said nothing whilst the US sanctioned Iraq to the point half a million children died in Iraq and the US secretary of state went on TV to tell people "it was worth it" and that they have literally murdered millions of muslims since they began funding the head chopping jihadis in the 80s where Osama Bin Laden built up his networks in the Muhajadeen
You don't owe these people anything and you should start viewing how you interact with them as a game for your entertainment
