Yes! I too have the same feeling towards Tigrians.
Why is the Tirgreans behave and act anti Ethiopian? Was it driven by inferiority complex? Was it driven by identity crissis? Or was it driven by their true love to Eritreans despite the Eritreans attitude of looking down on them? Or may be they have been treated by past Ethiopian rulers differently from the Amharas, Oromos, Gureges, Wolamos, Afars etc. One day in the future we may know the answer. I have said this because, in 1991 I happen to be in Italy, when TPLF & EPLF seize power in Addis & Eritrea. Then the mood among Ethiopians of different ethinic group, with the exception of Tigrians most of whom were educated, was anger and stress.
To their credit the Eritreans controlled their emotion and behaved well. What was surprising was the behaviour of Tigrians of Ethiopian origin. They have been strongly arguing in favor of Eritrea when ever they encountered any Ethiopian be it on the street, a bar or a public gathering. They have been cursing Ethiopinas as if they were their enemies. They were talking then how the Ertrean army was invincible, arguing the port of ASSAB belongs to Eritrean not to Ethiopia. Until then I have never question their Ethiopianess. That was not only a suprise for me but at the same time for the first time in my life I saw them differently with suspicion and anger.
I believe Ethiopia is good to them but not the contrary. Today 1/3 of Tirgrians live in main cities of Ethiopia in a better economical condition than they would live in Tigrai. One out of three Tigrean will migrate to Ethiopia to permanenly reside for the rest of his/her life. So why are they preaching for landlockdness of Ethiopia? Why they are not trusting us? Is the 1998 war agains Eritrean is not a proof that we care about them as our own?
