Power of followers (The Facebook Rainbow Symbol)

OK....wait. So i noticed that everyone has the rainbow over their profile pic and I asked if that means the person with the symbol over their profile picture if they are GAY or...Thinking about it? Whats up with the rainbow over the profile? When I posted this question on Facebook someone answered that "It means they support equality and equal rights for all." and another further explained that " Well it's mostly due to same sex marriage being legalized in the U.S." My rebuttal to that is So what happen to the equal sign wouldn't that suffice? Why the rainbow that most know an identify as the symbol for one that is living the alternative lifestyle? For instance I believe in freedom of religion therefore would it be ok to place a swastika on the face of my profile because it is a symbol for Hinduism, Buddhism and Jainism without being confronted by one that may know that symbol to be connected to the Nazi party that killed thousands of Jews? or would we say that's different? The response that someone gave was "Although most people who have that on their profile don't even know what it means, they just want to be like everyone else" Ahhh Haaa....that's what I figured but I just needed someone to admit this is what I am seeing when I look online and see all of these people doing this. See its not an attack on any group but growing up with what my H.S Teacher Ms. G taught us I just learned that everything isn't for everybody. Therefore one should truly research what they don't understand so that they know what they are standing up for...I wish more people would read The Wave and see how following one could lead to compete destruction. Cause what everyone else do could cause alot of confusion or issues. I truly believe the world has too many followers that one day we will wake up and ask ourselves what happen to our leaders.
