Hi Mabelsound,
Nope. In my opinion "the evil SLR" therm was not accidental nor the hostility to SLRs by a few members is accidental either. Both flowed from a feeling that RFF was becoming a "general photography" website, and thus in its way to the grave.
But facts proved differently. By not closing its doors, RFF continues to grow as an open minded rangefinder forum. RFF continues to grow - this is a stubborn fact. In fact the owner even opened many more subforums for different type of cameras.
Now, if I am correct, hystorically the SLR camera was a revolutionary improvement over the RF that opened many doors for science, medicine and pleasure, previously closed. However, like most advances in the camera industry the new breed did not included many advantages of the previous one.
This doesn't mean that the new is "evil", nor that the previous is "arcaic". This means that you can either complement both, or choose the one that not necessarily being the most advanced still better performs for your needs. Hence the objective place of Range Finder cameras, and film.
In general, most of the edges rangefinders still have over slrs is in their unsurpassable silent operation (although here the smaller mirrors in digital cameras may surprise one day), faster focusing, and the ability of seeing the image at the time the shutter is firing. Furthermore there are a certaing subcathegory of very compact and full featured RFs, that manual SLRs never matched.
All in all the differences of tastes about RFF were skillfully managed by the owner, so don't feel personally provoked when a nasty commentary about SLRs is voiced. There is a reason for its being nasty and another reason why nobody feels worried about it.
Cheers,
Ruben
