I agree. We are called not to judge the world, not to judge the "servant of Another" but to judge that which is in our responsibility. We judge our churches and guard against what we view to be false doctrine.
The problem is when people start attacking other people for the views they hold. Not only is this unbiblical, but this also damages our witness to others. God never blesses disobedience, but some people act as if they are God.
It all depends what you call 'attacking'. Just because I disagree with you and say so, and show you are mistaken, is just part of it. Call it what you like. I don't see how it is unbiblical. I don't see how it damages our witness. I don't see how it is disobedient.
If you cannot defend your position, maybe instead of believing others are attacking, you try and find out if your position is wrong, or can you do something to defend it more.
