No, it was not. I reject the idea that there is any sort of justification for the invasion of Ukraine by Russia. Ethnic Russians in Ukraine did not always have their Russian linguistic heritage trampled upon. In fact, many western Ukrainians who are not Russian can speak Russian language. You will know it if you know enough of them. Don't try to convince me that there is a grey area and responsibility for the conflict lies with both sides.
You can choose to believe what you want. But do not expect others to agree. They may indeed know more than you. You can never know for sure.
PS: Try to keep the conversation to Ukraine vs Russia conflict. As I've said many times in the past, I do not like the conversation moving in tangents.
