I think it's important that the word of wisdom is part of the covenant relationship with the Lord that a member of the LDS church makes. The language that the word of wisdom uses is that it is given specifically for the saints. The sin doesn't come from partaking of coffee, tea, alchohol, tobacco etc or eating unhealthy foods. It comes from breaking the covenant that a member of the LDS church makes when they decide to join the church. I think too many members don't understand this and tend to lump anyone that doesn't follow the word of wisdom as being a sinner and unfortunately they tend to judge them negatively for it which makes us seem holier than thou. The fact of the matter is that the rules are different for a mormon because they chose to live by a different set of rules. Those rules don't apply to non members and while I don't suggest that mormons start hanging out in bars as long as they don't drink. It would go a long way towards other people being more comfortable around mormons if they didn't act so retarded around people who drink, smoke, etc.
