What are the laws regarding jehovah's witnesses visiting people in Ireland?

Jehovahs witnesses, hereby referred to as JW's.

Everyone here has probably heard of these people, and many here may be familiar with this cults teachings already. The reason it's called a cult is because it is a false translation of the hebrew written bible (as opposed to the christian bible in english - which is a proper translation). The original bible does not mention that it's bad to smoke cigarettes, however the JW's rendition does have as a simple example.

The JW's that call to houses do believe this is the only true bible themselves; the JW's have a list of false prophecies dating back to 1914.

I believe (with my limited research) that they are trained to pick out vulnerable people - and also are trained to think a lot, for up to 5hrs even on how they will approach an individual to join. 

I got picked because I seem vulnerable due to autism, but i'm not an idiot, that's for sure. I said I wasn't interested when she came straight up to my front window, a few days later I got something in my postbox; even though I had already said I wasn't interested.

I heard that JW's help each other out with money and stuff if somebody is in trouble?

She's vulnerable and has depression; a horrible attitude towards anyone and two faced. Having depression in my imo does not mean you don't know what manipulation is.

She is my neighbour, I live in a community with vulnerable people and she is trying to get other people to join in the estate. 

Thanks very much for taking the time to read this
