I am thinking myself of being a peaceful guy. At the same time I believe to be a sincere person.
I realize that by being sincere it is hard to completely avoid creating aggression within others. But anyway, even if I try to avoid creating aggression at any cost, I can't. People are way too creative in seeing threats anywhere.
So solving the problem in the very beginning - by not creating aggression - is quite impossible. So one has to think about defense.
And the best defense is ... not be there (said by Myagi in Karate Kid).
I am quite sure that this is not always a convenient solution - not always feasible. But imagine people attacking you personally and imagine you are getting your self-confidence from somewhere else so the attack is not going to hurt you. Or imagine another company that is fighting you by producing cheaper than you. If you are innovative and can offer additional services or already newer, improved product then you moved to higher quality and the weapon of your opponent is simply obsolete.
Your first emotional action might be to defense yourself, your properties or your ideas even. Already the words "resistance" or "defense" come along with the feeling of effort and struggle. Getting yourself out of the fireline with a small step to side is often much more efficient and effective. Keep this in mind, before arming up for defense. However, when you know how to move out of the fireline you will also know when to stand up and fight - sometimes it can be necessary.
