I’m not sure what you feel like you’re adding with this reply.

Well done for making the effort. Thank you, and we all appreciate it.

But what do you want other people to take from this? Are you trying to discourage other people from taking action? Because you encountered resistance other people shouldn’t try at all, even though they might end up speaking to someone more receptive?

Even your MP may end up changing their mind if enough people speak up. The goal is not to single-handedly sway their opinion, it’s to add your voice to a growing chorus. You’re joining a movement, not fighting a solo battle.
