I’m going to limit my time on fruitless threads with people spouting me me me.
The trick is not to avoid certain threads but to avoid failing onto the trap of engaging directly with certain people.
You make your point, you back it up as strongly as you can and then step back. Remembering you are not arguing with certain posters but making a point that every reader out there (whether they post or not) can see.
The number one rule of forums is your audience isn't a single poster you comment in response to. Nor do you necessarily get a response to what you've said. If what you say has value others will appreciate someone saying something different. Silence doesn't mean a point hasn't struck a note. It's about trying to spark a thought process off in a number of people. And it can offer reassurance to others afraid to go against the grain.
I believe in the integrity of the truth and how that always ultimately shines through. Reality isn't something you can avoid.
I wanted to go into media when I was in my teens because I wanted to change the world and sure constant pursuit of trying to find the truth as integral to that. I didn't go into the media and I've not made any huge waves about changing the world. I do think that Internet forums have given me the opportunity to cause a few ripples though and to encourage others to try and think better and to question and seek out reality more. It's not ground shaking, but I'm not sure it needs to be either.
Everyone can participate and promote debate and challenge nonsense in their own ways and that as important as winning prizes for noble or valiant causes. Understanding that the world is difficult, hard, complicated and sometimes totally counter intuitive as a life skill is sometimes just enough.
