It likely helps to take in the cultural moment or context around the statements or the nature of the statements you're making. It's fine to state a fact but it's also helpful to make it clear whether you are saying "it is what it is " or "I wish things were different" or "I am doing X, Y, and Z to try and help and I recommend others do so". Jokes are an exception and I think misunderstandings are fine there. But it's unreasonable to think that on the Internet, people will "check to see if you are serious".
