You need to add "to me" at the end of your sentence here, because you're making it sound like you think their post sounds a certain way objectively, when that's actually subjective and didn't sound that way at all to me.
As a counterpoint, your recommendation could be similarly received as a command because you omitted the qualifiers indicating it was just your opinion.
In my opinion such qualifiers aren't necessary as there's an implicit understanding that others are sharing their opinions, and are generally explicit in the event that they're not.
