Firstly, as I said, different people hold different views on such things. Secondly, I haven't lowered any ratings, I simply said it made it harder for me to read those stories.
Thirdly, I guess you've spent most of your life around people who swear all the time. I don't think it makes it 'more "realistic" at all. There happens to be a large percentage of the world's population who don't talk that way. Where I live, it's rare to hear a swear word. When I grew up going to school, I'd almost never hear someone talk that way, and people who swore were reprimanded for their behavior. Among my family, and my friends, there's never a single swear word, and in any workplaces I've been in, people talking that way were considered to be acting inappropriately, and would get a warning about their behavior.
I don't find swearing dramatic, either. Plenty of books are dramatic and chocked full of character, plenty of movies too, and they didn't require it. Some people might like it, and that's fine, I won't hold it against them, I just find it harder to like what I'm reading. And I didn't mean that you had to use words like "Gee whiz". There's a difference between G-rated 'oh no, what will we do', simple curses like "Hell!" and "Dammit!", and stronger coarse language. Such differences are why things are rated G, PG, M and R. And as I pointed out, I took into account that Necromancer was rated 7 for maturity. I was just expressing my opinion.
Fourthly, I'll shut up now, or I'll go on all day.
