Its only Afaworki that has beef with Tigrayans.Due to Meles border wars with them. They were cool when they toppled Mengistu together.
Eritreans are cool with Tigrayans for two reasons.
1.Is during the war all of Ethiopia participated infact it was the Ethiopian parliament that took the decision to go into conflict.So it was an Ethiopian Vs Eritrea of which Amhara and Oromos fully supported.
2.The Eritreans have forgotten about the 20 year war all their memories is about how the dictator Afaworki stole their dreams and hopes and turned Eritrea into a concentration camp with no future in the horizon.So an Eritrean who escapes to Tigray has a better life.
