The foundation for sila for laypeople is the 5 precepts. Upholding the precepts and being mindful of them is training for sila. If they are easy for someone personally, that is great. But being easy doesn't diminish their worth, importance, and the respect we should afford to them. This is especially the case when encouraging others to refrain from breaking them. We wouldn't not tell non-Buddhists to "uphold the 5 precepts," but we can encourage refraining from killing, stealing, sexual misconduct, lying, and using intoxicants when the subject arises.
