...the problem with your assertion comes down to a basic failure in reasoning. You think that if I opine that watching violent video and playing violent games influences people in negative ways... I'm forcing my beliefs on others. Would you please show me the logic in how stating my belief is the same thing as forcing others to bend to my will? The reason your reasoning is faulty is that merely voicing an opinion or a belief isn't forcing anyone else to do anything. For example, if I say I dislike fast food, or that I believe fast food is a bad thing for our bodies, am I forcing people to bend to my beliefs? Aren't we here not just to debate, but to give voice to and share our opinions and beliefs? An opinion, a belief... can never be seen as a weapon to force others.... and deep down I think you already know this. Now, I can help you if you want, but it will take some effort on your part. First you must accept that within an online community, and that like it or not people will state their beliefs in order to share them with everyone else. Secondly, after you understand that, you should lower your sensitivity to the existence of other beliefs being vocalized in a civil and respectful manner. After that, then simply go with the flow, enjoy the varying perspectives and understandings, and learn. I'm relatively certain that once you adopt steps 1 & 2, you'll become a far more flexible and less dogmatic person, who will no longer see debate as some rigid battle, but an enjoyable mental exercise in learning.
