The Bolsheviks’ had the ill-gotten might to push their agenda, but might does not make right. The Bolsheviks lied to and used the anarchists to achieve what they did, but anarchists have learned from their past mistakes and will prove you wrong.
No amount of moralizing will change the fact that anarchists fail to organize effectively time and again. If anarchists actually learned anything then we'd see that put into practice. The lack of any actual achievements is the elephant in the room here.
Capitalist aggression did not make necessary the regressive views on social issues and science the USSR had (which resulted in famine), nor the widespread corruption and bureaucratic inefficiency of state officials. You cannot simply excuse all flaws of the USSR by blaming global capitalism.
Yes, it absolutely did as anybody with even minimal historical knowledge would know.
Revolutions require a critical mass of people to come together, and sometimes people who have different vision for the end goal find opportunities to work together as Bolsheviks and anarchists did. Lenin wrote extensively on the subject of when alliances should be formed. MLs don't have a problem working with anarchists, recognizing that there are common interests and that a time may come where such alliances may need to be rethought. The hate largely comes from the side of anarchists who refuse to work with MLs and spend their time trying to discredit the accomplishments of existing socialist states.
It's also worth noting that the reality in the west today is that both MLs and anarchists are an insignificant political minority. If the current system does end up collapsing in the near future, then fascism is the most likely outcome. While the left bickers, the right is rapidly growing in power in vast majority of western countries.
