Hortensia,
I think your views are spot on. As I've pointed out many times on this forum, as an athiest I never engage anyone in theistic or belief discussions when away from this site. Ever. This site is different; we come here to engage one another. I doubt if any of the other atheists on this site proactively engage any theists as well. I know lots of atheists and we keep that stuff to ourselves, partially out of respect for theists by primarily because we put that stuff to bed a long time ago and we simply don't waste our precious energy and gray matter on it.
My own rules of engagement on this site: First, I don't enter clearly theist/JW specific discussions. It is rude and disrespectful and a complete waste of time. Theism is irrational. It is only one step higher on the evolutionary scale for sentient beings than feelings. I won't tell any of the other atheists what to do, but it would likely tone down the rhetoric if atheists stayed out of clearly theist discussions (I mean, really, do we atheists have any desire to discuss scripture, the GB, the WT, OKM, Cross pollinating generations or whatever the hell they call it these days?). These things nauseate me and they comprise the vast majority of topics on this site.
Second, theists should show the same respect and restraint. Try not to enter scientific, economic, etc. discussions with nothing more than theist mantras, feelings and beliefs. That annoys the hell out of me. Bring facts or stay out of it. Most theists respect this.
Third, I don't post on topics for which I'm not a SME. That alone would solve a lot of issues on this site if others followed the same.
Finally, each discussion should be considered a debate. The rules of debating are essentially: a. facts; and b. the correct application/interpretation of facts. Facts it seems are vewy scawwy to theists. When the topic isn't theism, which is as stated highly irrational in the first place, facts are the only things that matter. No one, certainly not me, gives a rip about someone's feelings, beliefs, thoughts or one dimensional 'knowledge.' We get a LOT of that on ths site. So many rush to find the first article that supports their reactionary, emotional, irrational and intellectually lazy viewpoint rather than study the subject matter on a 360 degree basis before posting. Too many are intent on winning arguments rather than learning something.
Among other things, I've been an adjunct professor (2 collleges and lots of different subjects). One of the subjects I taught was analytical research and writing. My students knew that any definitive statement that wasn't supported by empirical data on a 360 basis (both supporting and not supporting their view/thesis) was going to be red-lined. Too many on this site think that their cherished feelings or beliefs are worthy of typing crap into the keyboard. They are mistaken. And I 'see" red whenever one of the theists makes definitive statements (typically about atheists) which are completely false and totally un-supported by the data. I guess they 'feel' and 'believe' the crap they sometimes post. It seems anathema to them to actually support defnitive statements with empirical data.
I don't post on many of the scientific discussions. Cofty, Snare and Viviane are much more capable than I.
