If you care for your freedom, you'll want a gov't that follows the Constitution. If others vote for policies that infringe on the Constitution, they are advocating for policies that infringe on your freedom. The natural thing to do when someone advocates for what infringes on your freedom is to debate them so there is a chance they'll advocate for safer policies for you. If you care about you, you’ll debate others on the chance they might come around to advocating policies that are safer for you.
In other words, if there is a threat to your safety, and you can prevent it by getting others to see how their policies are dangerous, wouldn’t you try to fend off the threat by debating them? I’m talking about the kind of threats that haven’t happened yet, but will happen somewhere down the line.
Politics is about freedom and safety, etc. If you care about the diverse communities that face diverse issues all over this country, then if you see some kind of a threat that they may face, wouldn’t you want to warn them? If you’re into warning them, then you’re someone who doesn’t mind debating them because it is for their own good.
I had to debate people all the time when I was trying to get out of an abusive relationship. I hated doing it, but I had to, otherwise how was I going to get out of the hell I had been living in for so long? No, this isn’t political, but the issue of getting people to see the light where they only see the dark is something common to causes that are both political and non political.
