The most powerful tool you’ll have in an argument is facts, that back you up. You don’t need to have people to back you up if you have the evidence.
If you are confronted with an opposing view, if you have a source, you can’t be wrong.
That’s why we source our posts on here. Some of the things we talk about aren’t within our expertise. If we source it though with accurate information, no one can question what we’re saying.
Eventually you may build up a credibility within circles of people but there will always be those new people who don’t know you know what you’re talking about. So don’t let your guard down, source everything and you’ll never be proven wrong.
