Where concepts like how huge components of transphobia arise from sexism and huge components of ableism arise from colonialism are used to basically state that there’s this Keystone that if you break it, you can break the whole arch and solve all the problems at once.
Defeat racism and you can destroy ableism, transphobia, homophobia and a few others. Defeat sexism and you can destroy transphobia, homophobia and fatphobia. The list goes on and on with the worst offender being those who think defeating class oppression can defeat every ism out there, racism, transphobia, fatphobia, homophobia, ableism, etc.
This, plainly speaking, is a load of rancid horseshit. There is no keystone. There is no oppression that you can eliminate that will wipe out all of or even most of the other ones. They may reduce some elements of those oppressions, but each and every single one of these systemic oppressions have integrated into the social consciousness of each of the societies they are a part of. They can and will continue in the absence of their sources and of their aggravating factors.
So by all means, bring up intersectionality and sourcing. Make it clear that colonialist racism, sexism, classism and etc caused these various oppressions to arise and influence to extremes each other. But don’t forget for a second that none of them are keystones. That eliminating racism, sexism and classism will not eliminate any single other oppression.
And that if you expect even one fucking person to drop their work and fight on these other oppressions or allow fuckery from others on these other oppressions to work on these so called keystones, you are an oppressive piece of shit and need to sit the fuck down and shut the fuck up.
