Just finished watching Man Utd vs Liverpool, we won 3-0! *cheer* but what do you guys make of Mascherano's sending of? Justified or not?

The ref is right and he certainly has the right to show mascherano the 2nd yellow.
Mascherano should have known that himself that running towards the ref for 20 yards to argued wit the ref decision and given a warning to back off while he insists protesting certainly sums up his day.Feel sorry for Rafa.

If all he genuinely asked was what was the yellow card for, as Ryan Babel says he did, then its ridiculous. If it was actual abuse at the ref rather than just questioning, then fair enough.
