Thank you, Carol. I think you will admit that is what I carefully avoided doing.

I can't admit it because I have not read the posts of yours that you are referencing. You asked me what term would be appropriate and I told you. I was not commenting on any of your posts other than to point out the incorrect useage of the term "fascist".

Sorry again I slipped into a bit of inappropriate & misleading nomenclature: though I feel your 'Islamism' is perhaps a bit too general in its implications & sounds a bit like tarring all with same brush in its avoidance of specificity, would you not agree?

No, I would not agree with this. Islamism is a very specific term and only applies to those Muslims who are engaging in it.

The addition of 'extremism' seems to me the best of the suggestions.

Muslim or Islamic extremists would be good terms to use, but "Islamist extremists" is redundant.
