No they are not literally invited but you already knew that Spazz. However you cannot deny that the Church is very heavily family oriented. It is one of its main tangents. That leads to a atmosphere or almost pressure if you will, to have large families.
Family is an important topic in the LDS church... not large families. If there is pressure to have a large family even if beyond what you can handle is self inflicted or misunderstood.
Have as big or small of a family as you want/need but that is between you and the Lord.
Also try to understand every situation is different and you don't know the whole story.
Sometimes there are couples that can handle a large family where things change due to job loss, injury, sickness, death, blablabla... things change.
Sometimes there are couples that can handle 3 children that things happen and they can't handle those 3 any more.
Life happens man.
Try not to judge when the whole story is not known.
In fact, I suggest you make up some story to explain it in a way that is satisfactory to you.
While most likely not true, it will help you not judge or react negatively to that person, family, situation, etc.
For instance, I imagine that Trout was hit on the head by a brick and after that he wanted to get into politics.
(Not really just saying that to you Stoked, just everyone in general)
