The folks who describe its as a “dreadful scourge” are almost always looking at it from an overall operational standpoint - what did it do to the way the park works, and how did it effect the AVERAGE guest experience - whereas you and the other advocates almost always pull it back to a strictly personal level.
Also, if one person says “I was always able to get the Passes I wanted, even during the busy season for last minute trips,” while another says, “I could never book the more popular rides, even several weeks out in the low season,” some degree of clouded memory is taking place on one (or both) parts.
And a note from upthread - you frequently reply to claims that standby is the only system that really works in the parks as constructed by telling the story of your first, miserable visit to WDW during the standby years. But as you explain, you went during the most crowded period and did no preparation. I’d point out that had you taken the same trip, at the most crowded period and with no advance planning, during the FP+ era, your experience would have been just as, if not more, miserable. If there is one indisputable point, it is that FP+ made things worse for those who did no advance planning at all.
