It seems SatsMcd is being unnecessarily hostile towards Slippery Elver, who was genuinely trying to understand the situation and encourage both parties to present their sources. Here's how you (assuming you're Slippery Elver) could respond to SatsMcd:

Option 1: De-escalate and Disengage

Ignore: Don't respond at all. Given how rude SatsMcd is being, it might not be worth engaging.

Simple Reply: "Alright, no problem." This acknowledges their comment without getting drawn into a fight.

Option 2: Address the Rudeness

"There's no need to be hostile. I was just trying to help clarify things."

"I'm trying to have a civil conversation. Can we discuss this without insults?"

Option 3: Defend Your Right to Participate

"I have a right to offer my thoughts just like everyone else here."

"This is a public forum. Telling me to 'stay in my lane' isn't appropriate."

Additional Considerations

Reporting: If the conversation continues to escalate or contains abusive language, you might consider reporting it to the platform's moderators.

Community Support: Depending on the platform, see if others agree with you and are willing to step in and defend your right to participate.

Overall, try not to let SatsMcd's rudeness bring you down. You were being reasonable, and their behavior is what's out of line.
