How are Evangelicals different there? They will probably change if they become the majority.
Well, let me put it this way. Here, Evangelical churches look like Catholic churches more than some liberal NO churches. Also, external stereothypes are nonexistant: tele-evangelists, excesive requests for donations, "HALLELUAH!"s, dances and similar nonsense during services...
Here, we have couple of mainstream religions: Eastern Orthodoxy, Roman Catholicism, Islam, Judaism, Lutheranism. Anything outside of these is regarded as: 1) individual's fad and sad attempt to be different 2) dangerous cult. Cults (as seen by Serbs) are: Jehova's Witnesses, Whatever-Day's Adventists, Mormons, Pentecostals, and many other that are generally seen as 'denominations' in the US. The goverment works hard to supress these cults - it can't ban them, but it does a lot to supress them through pamphlets, religious education and lectures. Examples.
1) Mormons. At least here in Serbia, they take their communion with bread and water. A friend of mine used to be with them, but then she returned to Orthodoxy.
2) Pentecostals. They are generally seen as lunatics. Supposing that someone has heard about them, that is.
3) Adventists. Problem. They've got their theological seminary here, and quite a number of 'prayer houses'. Very dangerous for non practicing Orthodox (and Catholics). Their typical strategy is: "Why do you listen to those silly priests who pray to icons, which is against 2nd commandment, in a language you don't understand [hymns are generally sung in church slavonics], and why do you have Liturgies on Sunday when you should have them on Saturday, like the commandments say?"
4) Jehova's Witnesses. The most dangerous cult around. Universally despised. Some of their strategies are quite demonic. Example 1: They enter some insane asylum and befriend someone who' mentally deranged. The parents of the patient are happy that someone is taking care of their child, so they place Jehova's Witnesses in their will, leaving them their entire estate. Example 2: They make friends with lonely old people. The children find out that the last will was changed (in Witnesses' favor) only when it's too late. Also, JW have the famous nasty habit of going door-to-door. Last and not least, they're famous for dropping their "hello how are you" facade once they find someone who resists their evil lure, turning into furious demons they really are.
Both Witnesses and Adventists like giving out plamphlets, especially around elementary/high schools, thus attracting young people. Fourtunatelly, this practice will reach a dead end once the religious education is in full swing (aka: once the teacher can explain that no one is praying to an icon but to the God/Saint on the icon and so on).
