That's in a perfect world...but no one said they needed to be offended first...you misunderstood...we are saying exactly the opposite, that we needed to be more cautious how we present our advice...I generally say I'm not an expert but in MY experience...yada blah...but I know I am always one to bottomline things and my irritation gets noticeable at times...I hope they deserve whatever because ya just can't fix stupid...they can't spell, or use most forms of punctuation or show respect, I try to not respond but not always..what the heck did they learn in school??? But I do say...stop doing x...because I want them to know whatever they need to change or the tort will die...I need them to know exactly that...I am not one to sugar coat things and if they don't like what I say or how I say it...you want your tort to live...then shut up and listen...now another drink is in the offing...Thinking on it more to pinpoint what I mean by hostile language, I think that it's heavily related to commands. Short, terse sentences straight up saying "Stop doing x. You're killing your tortoise." vs "From experience seeing x happen when y is done, I'd strongly advise to do z right away." As said above, both opinions and facts are stated as absolute law a lot of the time, from a place assuming direct authority
Once that command is given, the wall is already up, no matter how much reasoning and logic based on science and experience is given afterward. Best I think to start with reasoning, and expand on evidence if someone still has doubts. It's more effort in the long run to try to lower walls rather than not raising them to begin with
