These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Fridge Logic: Why did Raideen's designers put his sword and shield on the same arm, so that he can't use both at once?
Macekre: The show was heavily edited for American television. Most if not all the religious overtones of the show were altered. The villains were changed from demonic forces to an alien presence. And characters that were victims of demonic possession were aliens in disguise. Even Raideen's attacks were altered to more resemble science as opposed to mystical.
Even stranger, this Macekre was subtitles only, so anyone who was even slightly educated in Japanese and just needed subs to "fill the gaps" could spot the edits immediately. Due to this, and the fact that it only aired in the US on Japanese local community channels in a few cities, the fact that it ever aired at all was quickly forgotten by just about everyone.
Actually, the show left that ambiguous. Certainly churches and religious symbols didn't bother these demons, and conventional weapons did. Both interpretations are possible, and in fact are probably not mutually exclusive.
