indeed, and yet imprecision is most luxurious.

新馬克思主義

is it just me or are the subways & trains getting stopped between stations more often lately?

Stop me if I'm wrong, but wasn't there something of an industry-wide policy change after the horrific crash in Hyogo Prefecture last year?

Yikes, Denentoshi-sen is really bad isn't it.

I thought it was just the rain...

新馬克思主義

I usually go for 新マルクス主義 --> 新マル

This makes sense, although I've never heard anyone on the ground describe it that way.

Yikes, Denentoshi-sen is really bad isn't it.

It's one of the worst, especially if you are trying to get yourself aboard on one of the last stops before Shibuya. In the past, I rode the Seibu-Shinjuku line out to Tanashi, and that was absolute hell. Chuo is also supposed to be bad.

Also, The Marx Brothers and Karl Marx are both マルクス, even though the "proper" katakana would be マークス,which is what I use currently. I'm always thinking about using the switch to the ル, but that's a weird direction to plunge into.

I thought it was just the rain...

The rain just makes it more unbearable.

Den-en-toshi is indeed brutal. Surely there's some folk wisdom out there about which lines are best/worst in various respects? I've heard that the Odakyu line is notorious for chikan.

And while you're on the topic of various マル主義 don't forget マルバツ主義、the meritocratic ideology of rote memorization! Sadly, I can't claim to have invented the term.

新馬克思主義 - this was chinese

i used to think there should be a chiisai katakana ル used in words like car, marmelade, marx etc. not coz it'd be truer to the 'original' but it would help differenciate better say cooperation from corporation

I never liked the long アー　for "r" in katakana. I'm sure it sounds natural to some speakers of English but not to my American ears. My name is Richard and to me, the most prominent sound in the word is the "uRd" at the end. To replace that with アード doesn't sound anything like my name at all. リチャルド sounds better to me, even if it's close to ricardo. I think you should go with マルクス.

The アー for "r" corresponds more closely to British pronunciation than to American.

Think about how an English person would say these:
"Charles"
"Richard"
"Marx"
"car"
"marmalade"
etc.

Er → a is also a "gangsta" pronunciation. The true Brit trait is the reverse: Chiner, Indier, etc. Listen to World Service sometime, and you can hear it.
