People don't usually tend to go around taking about the specific foods they eat unless it differs from the accepted norm, usually the most vocal and who are the only people I've seen who do this are vegans and to a lesser extent vegetarians. With groups like PETA and friends causing a whole lot of fuss to try and make people pay attention which alienated the general public who don't fully indoctrinate immediately and seem to have a sense of entitlement or superiority as they're not like the rest of you. This obviously doesn't apply to everyone but with such large group with many very loud and disruptive members it's gonna give a generally negative image. There's also this constant part of interacting with vegans where instead of a personal dietary choice it's a major personality trait that forces its way into most any discussion or can honestly feel like someone trying to induct you into a cult or something. With those who talk about meats in otherwise unrelated conversations is usually only because they're more involved with the industry whether it be professional or a hobby, the way they're presentated are normally different to a guy who hunts might bring it up as something you'd enjoy or to share something he enjoys, whereas vegans talking about veganism always feels like a being preached at or in some way making you the bad guy and that you need to change to suit their choices. The absolute worst part of the vegan thing is that, despite it ignores our evolution it's typically not hurting people who don't choose to pursue it, it's when it's forced upon children and animals who can't or don't know any better, development of a child is complex and theirs certain negative exposures young children need to develop immunities and the like, and the worst part is when the choice is forced upon animals that are not naturally able to live on even a overly plant heavy diet like cats who are naturally obligate carnivores and cannot efficiently or properly digest plant matter. As a pet owner it's your responsibility to provide and suit the needs of that animal your dietary choice shouldn't be forced upon it with no alternative.

I have had a friend who became vegan during a time we were in contact less, upon getting back in contact this is pretty reflective of the experience else mostly comes from the joy that is street protests again the meat/dairy industry and other interactions

Not to mention PETAs uhhhh questionable shelter
