Forgive me if I’m misinterpreting your post but are you implying that republicans are marginalized? A group of predominantly white cisheteronormative Christians is the marginalized group? I don’t buy that for a second.
Since valid conservative viewpoints exist outside this segment you've just reduced in your stereotype, then yeah, you are powerful at personally enacting this marginalization while demonstrating precisely that it's your own projected ignorance which does so. Do try better at buying things before selling your product.
Can you further your argument by pointing me to conservative viewpoints that live outside of the white Christian capitalist hegemony? I have a hard time understanding how Republicanism is an inclusive ideology considering their platform and talking points the past few years.
