The opinion definitely leads to consequences...
The consequence of my statement above is that people who have read it are now playing the game, it doesn't have to be good or bad, it's simply the result following from my statement, a consequence. Really, there is no way around this unless said in a vacuum, which is still subjectable to arguments. Bro, we can take this to actual philosophers, if needed, but I say you are out of your depth here, especially since you think anonymity plays a part in responsibility. You being anonymous is largely irrelevant, all that is missing is your actual identity, but you are still an agent under your profile name, making comments, etc., on a public board, people reading what you say and then being influenced by it is a consequence from your action, your action being that you made the comment. Them being susceptible doesn't negate consequences that follow from your argument.
