"Is It Wrong to Carry a Mission? First Encounter with a Toxic Player in Warframe" I am a noob!

"Had my first encounter with a toxic player in Warframe today. I've been farming with Protea, using her turrets to clear everything quickly. I was running a defense mission, and out of nowhere, one of the players said, 'F*** you.' Naturally, I asked why, and he responded with, 'You don’t share; you must not be good at sharing.'

I’m honestly confused—am I in the wrong for carrying the mission and getting 60%+ of the kills in a four-man squad? This is the first time I’ve ever heard someone complain about something like this. Maybe I’m killing too many enemies without realizing it? For context, I’m only on day 27 of playing Warframe, so I’m still figuring things out."

Really just having fun with Protea and trying to push to see what she can do is all. Not really try hard or anything.

My MR is 8. Player was MR 18 that was toxic.
