When we see something, we should try to critically analyse that thing properly before making judgments.
For example, a person can say something like "taxes are too expensive" and another user might just dive in and disagree, failing to realise that we come from different parts of the world and how things are in one country or city may be different from the other. Therefore, our views will be different, and that is fine because that is how we can grow or get better.
We are in a forum where we don't expect everyone to understand all our thoughts and how we talk and share our ideas, which we should also try as much as we can; if we are stating an opinion, we should try to be as clear as everyone can understand, even if we can't satisfy everyone.
Using the example that you give, there will also be nothing wrong with saying that "my country's taxes are too expensive" instead of taxes are too expensive," so there will be a clarity of what you are pointing at.
No one is perfect; there are times one can be corrected in the form of an attack. You can either calmly point the member who misunderstood you in the right direction, or you can use the ignore button if the attack persists.
