Congratulations! Ten years is quite the accomplishment these days and I hope you will have many more happy wedding anniversaries to come 
Pondering leaving? Although I disagree with the way you express yourself at times, I admire anyone who is so willing to stand up for their beliefs. Instead of leaving, why not change your approach a bit? People aren't getting angry because of WHAT you say, they are getting angry because of how you say it.
Sometimes it is better to keep silent when you feel you are being personally attacked. The more you respond, the more cruel their comments will become. The more cruel their comments become, the more frustrated you will become. The more frustrated you become, the less people will take you seriously.
You must also remember that people have the right to their own opinions, whether you agree with them or not. You're not going to change the world by sitting in front of your computer, making rather harsh judgments about people whom you've never met. You can't win people over by being negative. Instead, be kind and focus on the positive parts of your beliefs. Take a step back once in awhile and think, "Hm, how would I feel if someone were saying these things to me? ...How can I rephrase this so it sounds more positive?"
I do hope you'll stay, Brenda. Although I am not Christian, I have found your everlasting presence in the forums a comfort, in a way. When I open a controversial thread, I know without a doubt that you're going to be there.
Maybe take a few days off from HubPages before you make your decision?
