I presume you mean specific examples?
Because I can give a lot of general ones, and I might be able to find examples of atheists shoving their views down my throat, assuming I can find the comments, but that take some time. They are less publicly active, admittedly, so other than stories like pro-choice activists smuggling jars of crap into a building to dump it on a pro-life convention or something of the sort (they were stopped) there isn't a lot you can find on the news.
I find that agnostics generally only force their pro-choice or pro-gay views on people whereas atheists are more prone to make declarative statements such as "God isn't real" or "Religious people are a bunch of stupid **** and the world would be better of without them" without backing up their views.
I find it sad that writing so much as "God bless" at the end of a comment on an internet article causes a multitude of insults and derogatory comments as well as such declarative statements as I mentioned above. It's a pity that there are so many atheists like that. I'm glad that few people on this forum seem to have that attitude.
Perhaps it isn't so much shoving views down others' throats as attacking views held by other people.
Sorry for the semi-rant. I am not trying to say that atheists and agnostics are bad or anything, just expressing my frustration with people who think they'll convert me to atheism by calling me an immoral idiot.
