bb: Seems to me demons do exist; and the best way to deal with them is as Luther and More direct: Simply dismiss them by ridicule. This saves one from “obsessing” about them....
Spirited: The same holds true for the Devil’s “human tools.”
And yet it seems we cannot press too far in that direction, for two reasons.
First, in the divine economy, to "dishonor" one's neighbor ultimately is to dishonor one's self.
Second, we cannot ever treat our correspondent as a mere bug to be squashed. For we have no way of knowing whether "today's 'bug'" might not turn out to be "tomorrow's 'saint.'"
Only God, Who sees from the eternal now, can know such things. Thus it seems to me we should simply just leave the issue to Him....
Our human duty is to love our neighbor as ourself. One would think that would be easy; but the fact is, it's hard....
Probably the best thing is to avoid "obsessing" of all kinds, and simply "let go and let God"....
Being guided by the Light of His Truth. No darkness can prevail against that.
