catmom, I know where you're coming from...we've heard it all too...people can be so horrible.
But then there are wonderful people too that have come up to me & were really encouraging(after hearing the ugly comments, these people were like a breath of fresh air

)
I think the rudest comments were when we used to live in Wisconsin...we only had 6 when we moved. Now we're in Texas & I hear more positive remarks than negative when I'm out with the family.
I don't know what it is with comapnies, though.....around Christmas 2005, my dh was fired after 8 1/2 yrs with a company. The company moved new people into higher up positions & they didn't like people that valued their families over their increasingly intrusive maniacal demands....so they started finding any little excuse to get rid of the employees who refused to sacrifice their family time.
We went through 6 months of unemployment ..while expecting #10.lol..
...but everyone here pulled together & we made it....dh has another job....doesn't pay as much as the other one, but we're all alot better off for it.
as far as overpopulation...my own opinion is that its a bunch of BS...I don't let it get to me when people try to tell me that I'm killing the planet for having alot of children.
I would never go up to a perfect stranger & tell them..."you should have a dozen kids b/c yaddah yaddah yaddah".....I don't, b/c I respect their freedom to make their own decisions for theirselves & their families(if they have any).
I mind my own business....and I think that it is a sad thing when people lack self-discipline and they don't mind theirs.
Catmom...just ignore the rudeness of others...don't let them get to you. You go have your family...these people are to be pitied b/c they do not realize all of the joys that they are missing out on. Hang in there

hugs
