The working masses appear in all shapes and sizes. How would you feel if someone was ruthlessly attacking the appearance of someone who has a resemblance to yourself, say that if you were a balding male with a receding hairline and people that you agree with and generally get along cordially make fun of trumps sons for their receding hairlines and do nothing but attack them for physical traits that coincidentally align with your own physical traits. Would you not feel slighted? Wouldn't you wonder if those you are working with are judging your physical form in the same manner as they judge the enemy?
We must fight for the liberation of the working class, and to help join our ranks and feel welcome, we must cast aside our discrimination for the other. This means fighting against racism, misogyny, ageism, xenophobia, homophobia, trans-phobia, discrimination against the disabled, and to struggle against the chauvinist lies of the capitalist class.
