The reason people respond like that is because, not only does it seem like you have a personal vendetta against BM, your argument seems to be based in the whole "your pet does all the work!" meme more than anything else. BM really, seriously isn't significantly easier than the average spec. You can swear up and down that the spec is more
forgiving than other specs and has a high damage baseline but ultimately to get the most out of the spec you need to put in just as much effort as any other DPS spec. There are several specs in the game that are candidates for being "easier than BM"; Frost Mage is an example. It's usually because BM actually has pretty involved cooldown management and most other specs do not.
BM is one of the most popular specs because, after Legion, it is the most appealing spec to most Hunters because it's most similar to the specs that came before Legion. Before Legion BM would compete with the other specs regularly. In MoP, for example, it was a back-and-forth between BM and SV. Three of the most major selling points for the Hunter class are: being ranged, being mobile, and having pets. BM best represents all three after Legion. It is maximally patronising to pretend that Hunters only play BM because they are all stupid and only want to play easy specs or something.
On that note: no one is actually demanding that BM remain an easy spec/be made easier. BM Hunters didn't ask for the massive pruning in Legion. How does it make sense that the developers "punish" BM Hunters with bad damage and bad scaling for being an easy spec yet all the decisions that made the spec easy were forced on the spec by developers? Instead of continually screwing BM Hunters on DPS why don't they actually add some nuance to the spec if they feel it is missing? Barbed Shot is a good start, Chimera Shot being baseline would be another good move.

No, it is not half your damage, because I said "a lot lower than 50%" and not "50%". Stop skipping over small details to try to exaggerate your point. You shat out a figure into the thread that is flat-out false by a big margin no matter how you look at it.
They are still things the Hunter has to do manually no matter how you spin it. I'm sure Frost Mage will pull a decent amount if you just press whatever lights up and any noob can do that. They aren't going to stack up to better Frost Mages in raid and probably other specs as well. Skill floors really aren't that relevant when to be competitive in any cutting edge content and not be benched you need to be at the skill ceiling.
EDIT: For what it's worth, I tried to attach an actual data point to this. I took the warcraftlogs ranking for every spec at its 10th percentile and compared it to the 90% data.
As expected, BM is one of the highest but not the highest. And the key takeaway here is that the variance is not that large across all specs. So it's not like crap BM Hunters are doing near equal to good BM Hunters.
