Vegans? Hypocrites?

I do not kno any full on vegans personally soo fellow CC help understand... so vegans do not eat animals and no animal "byproducts"...

First question why not the byproducts if it isn't hurting the animals... obviously not eggs cuz that unborn chickens and what not but milk? Cheese? Honey? Things like that why is that a No no...

I realized something as I was typing I was gunna relate breastfeeding to drinking cow milk but I realize cows feed cafes as to a woman feed a human baby soo yeah never mind that...

Second question do all vegans feel meat eaters are hypocrites especially ones that say they love animals but still go enjoy a double bacon cheese burger? ...

Third question fellow meat eaters/vegetarians how do you feel about vegan ways and beliefs, && could you see yourself going full on vegan ...
