There are two common statements by either trolls or low iq people. I will address them now.
1. "They took it down because it's a stupid conspiracy theory"
but the western media blasts anti Chinese conspiracies 24/7 - eating bats , eating pangolins, disgusting seafood market, Chinese bioweapon (which is the dumbest conspiracy theory of all). Obviously, only China-bashing conspiracies are allowed by the western controlled media.
2. "lol...ya ya, they use bioweapon to hurt themselves..."
There are many stupid actions by the western imperialists that backfired. We don't even need to look into conspiracies. For the past two months alone, hundreds of millions across the Western world ate popcorn and rejoiced as Chinese people died from the coronavirus. Yet, they did not prepare for the coronavirus. Now, they're desperate and thousands are dying.
During the 1990's, president clinton removed banking regulations that caused investment banking to ruin wild and turn industrial capitalism into finance capitalism across the usa. This culminated in the the usa destroying trillions in the global economy and greatly harming itself in the 2008 world financial crisis.
They learned nothing and punished a single Chinese small savings and loans bank that actually followed all the rules and allowed the criminals of the big banks off the hook.
Western governments doing stupid things that hurts themselves is very common and requires no conspiracy theory at all.
