Socialism is classically a major turn-off for conservatives. Why is that?

Detailed answers are appreciated. I understand the basic concept of not wanting to pay more in taxes for social programs you will not use, but why else? Thank you.

Edit: Yes, I phrased my question wrong. I was truly thinking of socialist-adjacent policy and not a full blown socialist system. Social policies have been labeled as simply “socialism” in the modern political zeitgeist, so my question followed that line of reasoning.

No, I don’t have a perfect understanding of what socialism means. That’s part why I made the post. Thank you for your attention to this matter.
