IF you flop bottom two pair on the flop, is there any reason not to make a substantial raise and go all in if you are raised? I figure only three of a kind has me beat, and I hold some of his outs if the cards help me at all. How do you guys play this when is happens?

Example: I call .50 with 7h,8h and flop comes 7d, 8c, Qh. I bet $3, got raised to $6 and went all in. He had 3 queens that he only called with on the first betting round. I felt in the long run that need to bet that strong and losing will occasionally happen. Do you guys go all in with bottom two pair?
