I figure there's a fairly big difference between disliking videogames because they don't appeal to you or whatever and actively opposing them purely because of what they are. I don't have a problem with people disliking videogames but opposing them is an outdated and stupid way to be... Mostly because almost everything they think/claim about videogames is bullshit.
I don't think I've ever seen anyone get harassed , but I have seen a discussion revolving around the "merits" of video games as a hobby. Fortunately, I surround myself with people that acknowledge that they are a waste of time as much as any entertainment medium, but also see the artistic integrity and pure fun that can be found in games.
Well me and my friends are all avid gamers, but it's silly to think that video games are less of a "waste of time" than watching a movie or reading a book. All entertainment medias can be considered a waste of time, but I think if it enriches your mind and life, who's anyone to judge?
Most people I've met who dislike video games use the excuse of it being a "waste of time", though the majority also watch movies and engage in other pointless hobbies. When it comes to arguments, I usually like to point out at their "waste of time" argument. As for being a supporter of the censors, that usually has nothing to do with anything. I vaguely remember a time when people thought gamers were the equivalent of losers. What did that have to do with supporting censorship? People disliked videogames before SOPA, ACTA and all other equivalent bills. This is just my opinion, though.
