When you ask a question when you already have an answer, do not be upset by the answers people give. Your questione
was phrased to attract them not those that support your opinion of the matter.
Your question was why doesn't anyone attack other faiths than your own. A look through this site can uncover a lot of negative posts about other faiths, one faith in particular. I had already seen three memes attacking that faith before I got to yours. Kinda took the wind out of your sails, as it showed your question was false.
Religion and politics will always be hot topics. If you wish to debate them, be prepared to deal in facts. But take into account that anything you say can be used against you. For example, I can quote scripture to you to back up my claim because that is the standard you bear. Quote scripture to me? Might as well quote the Brothers Grimm. I do not accept the Bible as being the gospel truth or the word of God.
But then, I feel the same way about the Qur'an, the Book of Mormon, and any number of other Holy Scriptures.
Not every meme makes it to page one. I've been lucky once, I've made it to page two a few times, and I usually end up with a meme on page three once a week. Disappointing? Sometimes. Accept what people do.
