Why are there no separatism/secession feelings in the Italian and French regions of Switzerland?

I asked on r/suisse but I didn't know there is also an italian language Swiss subreddit ( r/Svizzera was dead when I looked it up)

Here in Canada having two national languages is already quite complicated, and many people don't really respect those speaking the other languages, and especially a significant percentage of Quebecois want independence since decades, even if they were never in the majority (yet)

What isn't there similar feelings in the italian and french regions of Switzerland? Since Swiss germans are the majority, they can decide most of the laws and politics of the country, right?

Also, you guys have mandatory military service for men, how does that work out with three (four with Romansh, but it's < 0.5% of people) languages? Aren't there stereotypes and discrimination toward army members speaking another language?
