No, it's not that. The big mistake is people thinking personal experience is objective. For some, modern digital rigs are fully capable of delivering what they want from a rig and are in a fact superior tool/user experience. For others, traditional gear has distinct advantages that they are not likely to ever get from another type of rig. And there are those who can get there sound with almost anything. Tube amps will be around as long as tubes are viable to be manufactured for this reason, I would guess.
The religious wars, like all religious wars, start when enough members from one group, lacking any empathetic understanding for the others, says, what is right from my perspective SHOULD be right from EVERYONE ELSE's perspective.
Personally, I have ZERO use for tube amps after having used them for nearly twenty years. I am thankful for this era of gear and wish it had come sooner. That said, I totally understand that some people want traditional rigs and they will never go away. Just don't tell me your feelings about gear are somehow more valid than my own and we will get along great even if our opinions differ.
