In all seriousness though, that which is identified as "radical islamic terrorism" is such because it is perpetrated:
- By those self-identified as Islamic
- Targeting those identified as non-Islamic
- For the purpose of furthering ostensibly Islamic interests
For something to be justifiably identified as "radical _____ terrorism", I think you'd need to be able to accurately substitute "Islamic" in the bullet points above with another adjective. IE, radical Christians who bomb abortion clinics, or eco-terrorists who attack environmentally-unfriendly corporations.
