Is you national flag controversial in your country?

For example, in Germany and Spain, the flag is commonly associated to right-wing, while in Denmark or Finland it has a neutral connotation.

In Serbia I think the flag is positive, doesn't matter if you are pro-Vučić or not, pro-EU or pro-Russia. In Turkey as well, doesn't matter if you are Kemalist or Erdoganist. I think Albania is the same.

What about other countries? For example, Bulgaria seems to be less patriotic and they score quite low in surveys of willinginess to fight for their country.
