The main thing Christ told His followers to do was to preach the Kingdom of God to all nations and all people. When we choose to "love" our fellow man by not speaking out against a sinful behavior that could cost their eternity, are we loving them or taking the easy way out?
You said: "..it doesn't cost me anything to just love my fellow man as Jesus said we should."
Luke 6:31 tells us to "do unto others as you would have them do unto you"
If you were involved in a sinful activity would you rather that Christian friends and family leave you alone and let you reap the consequences of your actions (Enable you) or appeal to you in Christian love to change your sinful behavior?
Being a Christian involves getting more than your knees dirty.
Anyone who looks at homosexuality and sees it as part of God's plan for mankind is taking a very liberal approach to it. Ask a 13 year old child why men and women were created differently and you'll get an immediate answer. It isn't until one gets "an education" that common sense and logic is forced from them.
Having studied the Vedas - i.e. Hindu scriptures - for many years, I can assure you that you are completely, 100% percent wrong here. The most important Purana states that homosexual sex was created out of the anus of the secondary creator, Brahma, for destruction. In other words, it was created (as was everything) but for the purpose of allowing those with perverted desires to seek their fulfillment, but to their detriment.
Similarly, in the Bhagavad Gita, the Lord clearly states that the only sexual act pleasing to Him is that according to religious codes - legitimate marriage. The Manu Samhita - original legal codes - state that same sex acts are prohibited and legally punishable.
