2NL - Top two pair, stack off?

...and shoving folds every single hand we're ahead of, leaving behind only the hands that we're behind (with the standard deviation of 2NL overpair crackheadedness). That push looks awesome until it's called, and then it's only straights and sets.

I wasn't worried about folding hands that I had beat at this time. I figured that since my two pair was so low, I needed to protect it against pairs that might catch up. Is this reasoning incorrect?

This paired with my notion that villains at this level often overvalue oesd and fds, made me think pushing was correct.

Thanks for the responses, btw.
