Yes, you’re right. If a person lies about his military service, he probably lies about other matters as well.
If one were to hire a person who lied about his military service, for example, and if part of the hiring decision was based on the person’s military service, then you might end up hiring someone who likely will lie about other things, including: workplace thefts, treatment of co-workers, excuses for showing up to work late or missing work, about why a report or project is not being done on time, and so on, the list can go on.
The same is true elsewhere. A person (note, I do not say man) who lies about his military service to someone he marries may also lie about whether or not he cheats, has a mistress, is hiding money, is planning on using the relationship solely for financial gain, and again the list can go on.
This issue may not always seem like the most important one in the world, and probably isn’t to a lot of people sadly enough, but it is just one more example of how far our country has fallen morally and spiritually to the degree that people think that it is unimportant.
Sorry. As an attorney I can tell you, free speech includes the right to lie. Cops do it all the time when they are questioning suspects.
