Some fads are better, or more palatable, than others
I think the trouble with the 6.5 Creedmoor fad is that, while it has true merit, it has been so widely (and vocally) accepted and celebrated by folks who don't understand why it is so good, or don't care to use it for it's strengths.
I'm the first to laugh and reiterate the "6.5 Manbun" criticism because I have encountered a number of those folks first hand. They're usually young men, like myself, who have used AR's or their grandpa's 30-30 to kill a couple deer, hogs or coyotes and now are dropping $1500+ on precision rigs in 6.5 CM so they can go down to the range, get the tightest groups possible with factory ammo at 100 or 200 yds. Then kill a couple more deer with them. When asked why they selected the Creedmoor, the answer is some variation on, "*cough*scoff* It's just better, man!" while never deigning to make eye contact because my budget 7-08 which is grouping similarly is "ballistically inferior," and by association, so am I.
Ok... I may be over stating my case, but my experience iterates a justified frustration. You don't need a high BC, long range bullet to hunt whitetail. And no amount of tactical gear and technical jargon will justify choosing the wrong, or less right, tool if your comportment denotes intellectual superiority.
People who are truly invested and edjucated in their guns, be it long-developed hobby or full-fledged lifestyle, are, in my mind, justified in being frustrated with a mass influx of ignorance. Especially when the dollars being spent in that ignorance make waves in the industry.
*That is NOT to say that those who like and/or appreciate the 6.5 CM are ignorant. But it's one thing to go after something because it's popular to do so. It's another thing entirely to buy and use something for it's merits and intended purpose.*
BUT, after my diatribe, this IS America. You can freely spend your money however you like.
