My definition of colonialism generally involves people being subjugated and being treated as less and involuntarily part of an empire. People in Gibraltar are British citizens with full rights by definition.

Land borders that one doesn't like doesn't equate to colonialism. It's just a land border that you don't like. The people of Gibraltar voted almost 100% to be British on more than one occasion. Trying to make them not British is the definition of colonialism

Would you hold that standard towards Angola in 1973?

The vast majority of its inhabitants were portuguese citizens with the exact same rights and duties as any other portuguese citizen in Lisbon. The majority of that territory (and certainly the parts with most of the population) was portuguese for 500+ years.
