Good news, I've found the problem for you and it is indeed on ATS's side of things.
Here is a Feed Validation Service from W3C:
validator.w3.org...
I tested the two feeds I linked to above, and here were the results it gave me.
First, for the Breaking Alternative News feed:
Congratulations!
[Valid RSS] This is a valid RSS feed.
Recommendations
This feed is valid, but interoperability with the widest range of feed readers could be improved by implementing the following recommendations.
Your feed appears to be encoded as "utf-8", but your server is reporting "US-ASCII" [help]
Then for the Ancient & Lost Civilizations feed (
feeds.abovetopsecret.com...):
Sorry
This feed does not validate.
line 4, column 49: XML parsing error: :4:49: not well-formed (invalid token) [help]
AboveTopSecret.com New Topics In Ancient & Lost Civilizations
^
In addition, interoperability with the widest range of feed readers could be improved by implementing the following recommendation.
Your feed appears to be encoded as "utf-8", but your server is reporting "US-ASCII" [help]
The error it points out specifically (the formatting will probably screw it up in this post) is directly underneath the space following the "&" symbol
in the title.
Just to check to see if the problem was with the "&" symbol in the title of the feed, I checked another forum with this symbol in its RSS feed,
"Politicians & People" (
feeds.abovetopsecret.com...). Guess what?
Sorry
This feed does not validate.
line 4, column 53: XML parsing error: :4:53: not well-formed (invalid token) [help]

Once again the error is pinpointed to directly after the "&" symbol in the feed title. Try the service yourself above, it's the first link in this
post.
So the problem isn't on my end. Instead of asking why Thunderbird and Akregator won't handle it, I would ask how Apple's software works that it
does handle it, because it must be handling the code in a different way.
I tried three more RSS feed validators:
feedvalidator.org...
friendfeed.com...
carp.docs.geckotribe.com...
The first and third of these gave me the same thing as the one above: an error relating to the "&" symbol. The second one above did not give this
error. Again there must be some kind of discrepancy in how the feeds are being handled, but the problem preventing me and the other three RSS
validators from accepting the RSS feed can be fixed with a simple replacement of "&" with "and," at least according to the errors given.
The last validator above gave the following error message for the Ancient & Lost Civilizations feed:
[CaRP] XML error: XML_ERR_NAME_REQUIRED at line 1 -
But it gave no error for the Breaking Alternative News feed. You can try it yourself.
Also worth noting is that Thunderbird is made by Mozilla, the same people who make Firefox. My Firefox browser also will not load the latest threads
when I click on the RSS feed to save it in my browser. So Firefox is a pretty major browser and it's apparently not loading any RSS feed with a "&"
symbol in its title, just like three of the four validation websites I tried.
So as far as I can figure, that's your problem, and I even gave you a solution for it.
Do I get to come work for you guys now or what?
Can I at least get a working ancient civs feed on Thunderbird/Mozilla?
