They're offensive and miserable and they can never manage to say anything substantive. They are not paid a living wage, rather they're paid pennies per comment so they make a lot of them that all added up signify nothing at all.
This is seen on an item on FOX news site about FBI agents unanimous in disagreeing with Comey's decision to not recommend Hillary Clinton for prosecution after delivering a litany of federal crimes she committed, itself signifying nothing. The entire report reiterates what is already well known and internalized and not wort the internet space its printed on. Since FBI agents haven't actually done anything noticeable it's all sturm und drang. Tell us what FBI agents do about their collective disgust and that might be newsworthy.
Back to what a troll looks like, and they too can be simply ignored because there is nothing of substance there, they look exactly like this:
The dope opens an account twelve days ago and frenetically makes 2,600 posts, goes back and "likes" himself. That is, masturbates on online and splooges all over the place. You can tell because nobody bothered to share a single post.
This is what the Democrat party brings us. This is their contribution to discussion.
