It is good that haters of Muslims like May now feel the need to deny that that is what they are. The next step would be to make arguments which don't turn around and make that clear.
Kremlinology (more common than Sovietology) was an attempt to understand what a particular secretive government was doing. May begins by pretending he is only after a small group of Muslims waging war against us, but throughout the article this expands so that diverse groups not all of whom are doing anything against us all wind up falling under the banner. To compare studying all of these groups to Sovietology requires a complete misunderstanding of what Sovietology was, or what the Muslim threat is, or both.
