It's too bad because they so poorly represent the Reformed School of Christianity (eg. Spurgeon, Pink, etc --very considrate persons in the past). These radicals are totally fixated on the five points of Calvinism with a meager understanding of spiritual dynamics (eg. fruits of the Spirit, walk in the Spirit, spiritual growth, carnality vs. spirituality, confession of sin, modus operandi of the Christian life) and other parts of Scripture. These late 20th Century hyper-Calvinists are to truly be avoided. Don't get in the mud with them.
I can understand your rational very well.
A fitting exhortation, imho.
