Is it safe to share a transaction ID?

As someone who is new to the world of cryptocurrency, I'm curious about the safety of sharing transaction IDs. Could you explain why some people might be hesitant to share them, and what steps I should take to ensure my own security when sharing this information? I understand that transaction IDs are a unique identifier for each transaction on the blockchain, but I'm not sure if this makes them inherently SAFE or risky to share. Thank you for your insights.
