You can't just tell everyone you disagree with that their opinions don't matter.
I can, I have, and I will again.
Especially if their argument concerns me, and is also inaccurate.
But what if your argument concerns them?
Usually, when people commit terrible sin, they often try to convince themselves that it wasn't that bad, and it often takes someone from an outside perspective to explain to them "No, it was that bad, you need to get to confession immediately" (speaking from experience there). So, if loving your own gender is, indeed, a sin, then maybe you're just trying to reason with yourself and therefore your opinions don't matter. Right?
Oh gosh, just typing that example ticked me off and I'm not even gay No, your opinions matter just as much as anyone else's. The topic does concern you, so, therefore, your voice should be heard even if there's a chance it might be incorrect.
So if people can just silence anyone they disagree with, then you, Jynnie, have been silenced. You aren't Dom and can't have an opinion on his opinion because that would be an opinion and I disagree with it so therefore the opinion on an opinion isn't a valid opinion, in my opinion.
…Do you see how ridiculous and offensive that is? Probably not because I'm terrible at explaining stuff
That debate involved Christians, gays, and gay Christians. We weren't getting angry when non-Christian gays got involved, you shouldn't be angry that non-gay Christians got involved as well.
