Hey Ads,
You can expect that BS to come out no matter where you work. If you have some size on you, it could be that they are insecure. Insecure people will usually put others down as they are not happy. In addition, they can't blame 'High stress' work for what they do on the weekend. Personally, i'd do a million cycles than do what they're doing over the weekend. At least with a cycle, you know where it's coming from and what you have to do to control it. I'm all for it. In all honesty, it's none of their business really.
If you don't like something they say, do what i do. Don't say anything and just smile then look away. That tends to burn them a bit as they don't get a reaction from you. Then it just gets boring for them and they move onto someone else. You'll have the upper hand i promise you. :)
I understand u have a respect for your team. Where i work, i have to trust my team with my life. Don't forget, if ur working in a high stress environment, people try their hardest to remain detached from what they're working on so they make jokes. Everyone thinks their opinion is the right one. Just keep doing what you want to do, and what makes you happy. :)

People are like sausages, it's what's under the skin that matters. Therefore, you should poke them with a fork periodically.
Drinking beer makes you feel the way you want to feel, when you're not drinking beer.
