It doesn't sound to me like Marisa's comment "Forced basking is not safe for your turtle!" was meant as disrespect. She was just making a point as to the important of not forcing a turtle to bask.
Unfortunately, when we communicate in writing only (as we do here), only the words themselves communicate. Not using enough descriptive words can leave alot open to interpretation by the reader. In order to get a point across, some will use punctuation, such as an exclamation point (!) to indicate the importance of what they are saying. If we were to add a smiley icon so the comment doesn't seem harsh, it may be interpreted as "not so serious".
It's hard to picture what someone is describing when we are not actually seeing what is being described. As you said, Heather, in cases like that, others here are just taking a best guess as to what is being "said".
Because of that, when advice is given and the importance of it is conveyed with strong punctuation, it can be construed as critizism. Which I don't think is the case the majority of the time.
