Umm... No thank you.
Personally, I feel that this kind of evangelical preaching is itself a form of intolerance, in the sense that here we have a person who it seems is strongly committed to his or her religious beliefs (no problems with that) who clearly feels that anyone who doesn't agree with their beliefs is wrong.
In setting out to convert people in this manner, they're showing an unwillingness to tolerate those who disagree with their belief system.
To the OP, may I suggest that you avoid preaching and decreeing those who disagree wrong, and instead debate and discuss these issues in a more... open and enlightened manner with those who wish to do so.
