I would give a different answer to this if it were in the cash or tourney section.
Since it is in the Learning Poker section I will answer it this way;
You have to understand that there are players who are
gambling. Some are new, some are very experienced. The noobs might not know better, and the very experienced are testing you, tempting you to do stupid stuff.
So the easiest thing to do, is to stop raising those hands you want to play. Just limp in, try to catch on the flop, and proceed from there. Everybody wants to see a flop, I want to see a flop. I want to see a cheap flop.
The math in the game is NOT THE GAME. The people in the game ARE THE GAME! The math can help you a lot playing the situation, but less so the people.
But then this is one of the beautiful things about poker.
