Sharing Your Opinion or Brutal Attack?

It is good to be politically informed and I respect people who have strong believes and opinions about issues that affect us all. When it comes to the political spectrum I am pretty moderate and take my stand depending on what the issue is. To be honest, I don't know enough about a lot of topics and am not informed enough to have a strong opinions about them.

One issue that I know where I stand is gay marriage. It's a human rights issue to me and it seems like there is no reason two men or women shouldn't be able to get married.
With that being said I respect people who disagree with me and have the opposite view (on this issue and any other). What I don't like, and what I think hurts the cause, are extremist who attack the other sides view and make it seem, that because they think something different, they are stupid and dumb. 

While I was on facebook today I saw this picture:

While I agree that many of the religious reason people think gay marriage shouldn't be legalized don't always make the most sense everyone is initiated to there own religious believes and I understand the importance of being religious. The way this poster is worded seems awfully disrespectful to me. I am filled with mixed emotion, on one hand I do agree that homosexuality is in NO way sinful, the point of the poster. But on the other hand the flow map is telling people that their religious beliefs are completely invalid in a snarky and disrespectful way. The points could be written in a more respectful way to help make the argument more persuasive. It just kills me to see this because it turns a good thing, supporting gay rights, into a disrespectful attack on others beliefs. This isn't the way to get people to change their mind, especially when, things like religious beliefs are deep rooted and are unlikely to change. Unfortunately  many people who are against homosexuality because of religious reason or because they think it is gross aren't going to just change there mind like that and an attacking sassy statement like this just cause more tension and conflict that help. I wish people, especially those with strong believes, could step back for a second and but themselves in the other sides shoes. Then maybe we could have civil conversations and resolve issues like this more reasonable... 

Hopefully one day we will be able to talk civilly and find a solution to this issues. Until then we will just have to work to be respectful and let majority rule.....
