A Boomer is a person of a specific generation. To state that this is AKA "someone who sticks to an outdated view of things and doenst engage with change" is so obviously prejudicial I'm not quite sure what your defence is supposed to be.
With regard to people needing to make an argument to justify expressing their preferences or dislikes, I think that speaks to your evident confusion of the subjective with the objective.
I'll give you another example of something that is not an argument, though, and why I thought you not worth engaging with:
but your criticism of divinity is a major case of OLD THING GOOD, NEW THING BAD
To which i canonly reply: Ok Boomer.
What that is, is a blatant straw man (in caps lock, naturally) followed by an ad hominem based on a person's age. The rest of it just a list of things you happen to find implausible about Forgotten Realms, with an extra ad hominem about the creator being a "fetishistic hippie". So, I'm afraid I just find it all rather snide, smug, and not very credible.
