The current default “Homepage” value is “All”. That makes sense for users with zero subscribed magazines, so they see something.
But for users with one or more subscribed magazines, the default value for “Homepage” needs to be “Subscriptions”.
That’s partially just because subscriptions mean little if the default frontpage ignores them. But there’s a more important reason than that.
The current situation is that posts in m/Conservative are heavily downvoted, and barely upvoted. (Whatever your politics may be, consider if this was happening to you.) As more ex-redditors join, this problem is likely to worsen.
Eventually moderators need better controls, to say things like “Only members can vote”, etc.
But for now, a very easy fix is to change the default value of “Homepage” to be “Subscriptions”. Of course, “All” should still be a selectable option for those who prefer it.
I think people are just seeing the posts and downvoting because they dislike it. A lot of the early magazines here that existed when I first joined catered toward people that conservatives shun at best and actively discriminate against at worst. I think those people don’t feel good about it so you see downvotes. I’m sure that given enough time you can show them that your brand of conservatism doesn’t mean shunning them with discriminatory and hateful social conservatism.
