There are any number of ways to reach out to people about the reckless dogma of the JW's and the history of the WTBTS then shouting outside or inside a KH.
In my own case I have been invited on occasion to give a brief presentation and Q & A session about the ten years I spent as a JW......as a pioneer and multi tasked Elder half of that time. However, in all candor, I have learned more about my old religion during the 7 or so years I have spent with you guys on this forum.
An open and accurate conversation about the practices and beliefs of the JW's with people, usually in other churches, who wanted to understand what they are about is very productive.
It's interesting that the JW's are not known for their message nor their Jehovah God.
They are known for not celebrating holidays, birthdays etc.
For refusing blood transfusions.
They are known for their door knocking but not in a favorable light. Nor could anyone remember anything they had to say.
There is a growing awareness of a pedophile problem but not that the JW's allow a repentant child molester to knock on people's doors. Nor did they know that for decades the JW's were told not to report child sexual abuse to the police etc.
I usually leave them with some of the crazy things you can be DFed for such as me visiting that church group talking about the pro's and con of the JW construct.
That If a JW visits their church and sits through a service they could be DF for that. Indicate t0 the Elders that you are going to become a member of the church I am addressing and you will be known as an apostate and shunned for life.
But what really get's to them (lol) is that those nice looking mannerly JW's who are knocking on your door are also checking out your property to see if they should move in after you are destroyed in Armageddon.
When its personal it really hits home.
You don't have to shout or be a verbal bully to make your point.
Admittedly speaking candidly to a JW does trigger their cognitive dissonance.....but that's their problem.
