The large leftist mobilisations that I recall are wto (against globalization), anti Iraq war (against imperialism and islamphobia), occupy wall street (against income inequality), pipeline acess protest (against global warming), BLM (prison and police abolishment) and Palestine (against colonization). These movements all are for the common good. BLM is tied to abolishing police and prisons. Anti racists have been attempting to abolish coerced and unpaid labor in prisons and ice centers. Raising the minimum wage would never reach those people. These other systems of abuse are entwined with class.
There is also a difference between identity politics and anti racism. Anti racism feminism queer activism or what have you are attempting to change the systems that cause the abuse. If anti racism is prison abolishment then identity politics is hiring a black warden. There is also the issue that bigotry if unopposed harms people. people cannot just ignore it. You will probably find if you center bigots you will lose many others. Opposing bigotry is not tearing society apart it is the bigots. I would urge you to read more about the theory behind these movments and imagine a world where a class war is won by bigots and the resulting outcome and the society that comes of it. Without education we will likely recreate our suffering again. I do not really debate and we have probably had as much useful dialogue as is possible.
