That woud depend entirely on what exactly was said and the full context of the message. If you are asking if you can sue for money damages, however, the answer is almost certainly, "no," because you have no money damages from it.

IF the case has merit [likelihood of winning and the other side found liable], value [substantial provable damages, such as injuries and financial losses] and collectability [defendant with sufficient insurance coverage or available assets to collect against], feel free to contact me if serious about getting counsel.
