People would use "Hide all political posts and comments" more often than any other filter

Is there an option to filter by keyword? Not on the app I use, but is that a Lemmy/kbin/etc feature that the app just doesn’t implement? I’d love to filter any mention of:

• Leftist/right-wing/alt-left/alt-right

• Nazis

• Capitalism

• Trump

• Trudeau

• Biden

• LGBT+ (let’s be honest, 99% of content mentioning it is ragebait/political/controversial in some way)

• Gun control

• Abortion

The list goes on. I’d probably end up with like two posts a day on my feed but damn would those posts be peaceful.
