URLs for Christian Polemic Repositories

This post may be considered as a follow-up for a previous post of mine , which unfortunately was closed because it did not "focuses on one problem only". Okay, let me rephrase my question to try to make it both more focused, and more politically correct: **Are there any well known online Christian Polemic repositories that have the talking points that can be used to counter the proselytizers of non-Christian faiths who are targeting Christians?** I know that there are a lot of sites with apologetics talking points, but I am looking for sites with polemics talking points.
