Defenses of religious positions using reason. This tag should only be used with respect to disagreements with religions other than Christianity.
Apologetics is the discipline of defending a position (often religious) through the systematic use of reason. Those who engage in apologetics are called apologists.
Usage: Do not apply this tag to questions regarding the defense of a particular belief in the context of debate within Christianity, broadly defined. That is, this tag does not apply to debates between Protestants and Jehovah's witnesses, nor between Catholics and Mormons.
The linked question was (and I agree that I'm reading a bit into it since the question doesn't specifically say this) asking for help discovering information in support of the OP's personal, assumedly pro-Christian, beliefs.
I would like to ignore the controversial nature of the request and his second paragraph, an attempt to avoid a fight by picking a fight, for the consideration of this discussion.
Question: How can we improve the apologetics description and wiki so that we have a more definitive description of our intent for the tag's use on this site?
It is my supposition that this tag's purpose is specifically to identify questions seeking assistance with developing an Apologetic argument. (I've asked a second Meta question about creating a new tag for asking questions about the field of Apologetics.) Therefore, to provide a starting point for comment and modification, please consider the following:
This tag identifies questions that are seeking assistance with developing an Apologetic argument. This tag may only be used to seek assistance developing arguments between two groups: one identifying itself as Christian and one specifically identifying itself as NOT Christian.
Apologetics is the religious discipline of defending religious doctrines through systematic argumentation and discourse. Early Christian writers (c. 120–220) who defended their beliefs against critics and recommended their faith to outsiders were called Christian apologists. In 21st-century usage, apologetics is often identified with debates over religion and theology. (Source: Wikipedia)
Christianity.SE is dedicated to understanding the many traditions and denominations of Christianity. This tag may NOT be used to justify debates or arguments between any groups identifying themselves as Christian. To that end, there are several guidelines that help make a good apologetic question:
The two opposing belief systems must be defined. One must be a Christian tradition or denomination. The other must not identify as Christian. An unacceptable question would identify two identified Christian sects (e.g., Catholocism and Mormonism). An acceptable question would be, for example, between Catholocism and Islam, Mormonism and Judiasm, or Protestantism and Atheism.
Apologetic quesitons between an identified Christian tradition and a political platform, philosophy, or movement are on-topic, but we recommend caution, courtesy, and deference when asking the question due to the frequently high emotion these questions incur. Questions deemed argumentative, offensive, or asked in poor taste, may be closed.
Apologetic questions should be very specific about the kind of information they ask for. It is not the goal of this site to write your argument for you. But we welcome the opportunity to help you gather the information you need to write your apology yourself.
Apologetic questions must always include a brief description (no more than 2-3 sentences) of their apology. Said another way, you must explain the goal of your thesis so we understand the context of your request.
The second bullet is most relevant to the linked question. I dare say I might have put the cart before the horse by suggesting improvements to the tag befor asking whether or not Christian-vs-Politics apologetics questions are even on/off-topic.
An example question following these rules and based off the linked question might be:
Pro: Southern Baptist Convention
Con: LGBT Political Movement
Apology: The Gospel of Jesus Christ is an effective method for strengthening mind and body against homosexual temptation.
Request: I am seeking information in the form of published reports, documentation, or journalism demonstrating homosexual relapse is lower than that of alcohol abusers.
My thanks to @PeterTurner for the basic phraseology of that request, which can be found in the linked question's comments.
