What opinions do you mean specifically? The question you asked is too vague to help us sort out the welcome from the unwelcome.
Remember: “lower taxes for businesses” is a mainstream conservative opinion, but so are “children should not be allowed to know of the existence of gay people” and also “Breonna Taylor probably deserved to die” and also “Dr. Fauci is a mass murderer” and also “Trump won in 2020” and also “more brown children should be put in those cages”, etc., etc., etc.
If the conservative mainstream is so hateful and bigoted that most of their opinions would not be allowed on a well-regulated platform, that is not the fault of the platform and it does not suggest that the platform has to change just to accommodate conservatives.
