Be the judge and decide who is trolling who from the below comment thread. As you can see, three community members are trying to help a fellow user to let him understand that Wikipedia is not a valid source here. We tried giving him links on why we concluded so. Still, the user repeatedly argued with us. The whole comment thread is the same to and fro insisting on valid sources. I feel the user is a troller as I felt the user is trying to start an argument instead of understanding community but do suggest your thoughts.
Note: This has nothing to do with the user's identity.
Edit: Taking Rickross suggestion, I tried emphasizing on
this community which clearly proved this user is a troller.
