This isn't bizarre at all, you'll see similar things before discussing any emotionally charged topic. People will preface an argument with "of course pedophiles are bad..." before explaining why the latest anti-encryption law is bad or "of course racism is bad" before explaining why some racial quota system is counterproductive or similar things for pollution, homelessness, drug abuse, war, etc. It's a simple thing to help the reader understand the perspective the author is coming from, especially useful when the author knows they might otherwise be lumped into some category they want to avoid being grouped with.
