do people want to read what you have to say? if so, you have some chance of convincing them to use tech that allows them to read your stuff.
if you're hoping that someone else's relay or client will present you with the engagement you desire, sorry, they have no specific obligation to you.
are you trying to talk to people that don't want to listen? that's no one else's problem to deal with.
No, I don't want to talk to people that don't want to listen. I want the users to be able to see my posts by default and decide for themselves. Instead, in the fediverse situation, for example, the default for the mainstream servers is to block all right-wingers. This is not true yet for nostr, but I'm afraid that it is possible via a client "nostrblock".
Nostr seems like a good solution.
there are many clients. encourage that diversity. try different options. engage with the devs about features and problems. fork your own that has improvements or simplifications.
there are many relays. post to multiple. use the bridges nostr:npub1q3sle0kvfsehgsuexttt3ugjd8xdklxfwwkh559wxckmzddywnws6cd26p built. run your own relay.
you will still have to work with people so they can find you. but that's just being a person.
