Why is Hinduism so quick to be called mythology when Christianity, Judaism, and Islam have less facts.?

People are so quick to Judge Hinduism for some Odd reason, when they don't know a thing about it. It makes me wonder, since Hinduism throughout history has done more for human kind than all other religions combined. We don't believe in killing animals which shows love and kindness. We don't believe in war, or discrimination which shows that we are very secure with our knowledge. We don't need facts to worship a religion like most of the new generation. We don't believe in polygamy. We have a ancient religion which is bring worshiped from the day god created it. We find ancient city's where Lord Krishna lived, but people are quick to dismiss our faith instead of taking a good look at theirs. I don't understand this complexity that people have for one an other. Its just not right. Why do people only criticize others when they can't begin to look at themselves. Is it because they have nothing worth criticizing in themselves, or are they just hollow and ashamed of what they might uncover ?
